Fine-Tuning the Adjustment of Passive Humbuckers

Posted on by Adam Gotch

adjusting guitar pickups

It’s been said that the best things in life are free, and I find that saying is never more true than when applied to getting a better tone from our guitars. With so many products on the market that claim to improve guitar tone in one way or another – from fancy new picks made from exotic materials, to super-rare new old stock amplifier tubes someone discovered in a factory basement – it’s a relief to remember that we often can make just as big an impact for free with nothing more than a screwdriver and a few spare minutes.

I am, of course, referring to the ancient and noble art of pickup adjustment.

Passive magnetic guitar pickups work by detecting the velocity of string vibration and converting it to an electrical signal via Faraday’s Law of electromagnetic induction. If that reads like it was written by someone who just Googled it themselves, well… There is a lot of technical information that explains this process, much of which can be gleaned from academic resources and other SD blog articles, so I won’t repeat it here. What I will say is that our pickups “hear” string vibration through an electromagnetic field around our strings. Making adjustments to our pickups changes the shape of that field, which, in turn, changes what the pickup hears and thus, changes our tone.

There are many, many different styles and models of electric guitar pickup (which, if you’re reading the Seymour Duncan blog, should not be news to you), and they each have their own levels and methods of adjustment. For the purpose of brevity, we’ll focus specifically on fine-tuning the adjustment of the common passive humbucking pickup.

Generic Statistical Image

“You see, Sally, this line I’ve drawn here represents nothing at all.”

In a surprising figure supported by no real data whatsoever aside from my own personal hunch after having consulted nobody, it is estimated that fewer than 50% of people who own an electric are even aware that the humbuckers are adjustable, let alone make any attempt to adjust them themselves. For the other  > 50%, here is how I imagine most pickup adjustments are performed:

Guitar owner turns screws on either side of pickup, plays a few notes, declares “YEP IT’S NOT TOUCHING THE STRINGS AND IT SEEMS LOUD ENOUGH I AM DONE NOW I THINK I WANT TO HAVE TACOS FOR LUNCH.”

That would do in a pinch I suppose, but what enthusiasm our hypothetical straw man has for taco lunches, he is lacking for some key aspects of pickup adjustment. I want you to have your tone and your tacos, so what follows is my preferred, in-depth method for humbucker adjustment.

Adjusting for Balance

Balance in this case refers to consistent string-to-string volume. Ideally, with a balanced pickup, one can strum all six (or seven or eight) strings and hear each note ring out with even volume through an amplifier. Balanced string-to-string output is good. It makes our chords sound fuller, our runs and leads more consistent, and helps the guitar respond more evenly, like a higher-quality instrument.

Some guitars happily exhibit this trait acoustically, but even those that don’t can be adjusted so that they do through an amp, and that’s really what matters, right?

String-to-string balance is manipulated via the screw poles in the top of the pickup. Again, designs vary, but they all function about the same.

• If the pickup has flat-head screw poles, we’ll need a flat-head screwdriver.

• If the pickup has Philips-head screw poles, we’ll need a Philips screwdriver.

• If the pickup has hex key poles, we’ll need a hex key of the appropriate size.

• If the pickup has two rows of screw poles, or twice as many crammed into one row (I’m looking at you, Carvin), we’ll need a little extra patience.

• If the pickup just has two rows of non-adjustable slug poles, we need some better pickups.

The screw poles are named so because they are screws; they are screws because they’re meant to turn, and turning them is how we adjust the string-to-string balance of the pickup. Kind of like putting on pants before putting on shoes, I find it’s best to begin with this step so as to avoid messing up other adjustments we will have already made by doing it later.

So, plug in your guitar and turn them.

Tweak them just enough that the strings all sound like they’re ringing out at the same volume when each one is plucked individually. It’s fine to use a guitar amp to monitor this and trust your ears, but I prefer to use something that gives me a visual readout of the string volume (like an audio workstation or any other piece of equipment with a dB meter) as I make adjustments. I pluck a string, note what the dB meter reads, and adjust the screw pole until it matches the meter readings of the rest of the strings. This way I ensure that my adjustments are accurate and my results are not affected by any compression inherent in a particular amplifier.

The blue waveform on top was recorded prior to adjustment. Note how much smaller the output differential (highlighted area) is on the green waveform, which was recorded after adjustment.

If the screw poles in the pickup were already adjusted by someone else or are all wonky for whatever reason, “reset” them by screwing them all back to a position where they’re slightly higher than level with the surface of the pickup bobbin. This way there’s plenty of room to adjust up, but also a little bit of room to adjust down without sinking the poles too far below the surface of the bobbin (which looks weird and can collect gunk over time). The goal is to find a mean depth for all the screw poles, so that none of them wind up too high or too low relative to the function of the guitar when finished.

Adjusting for Output

photo depicting pickup height adjustment

Once we’ve balanced the poles for string-to-string volume, we can adjust the overall height of the pickup for the desired output level. Output refers to the strength of the guitar’s signal from the pickups. More output = a hotter signal. This typically equates to more volume in a clean setup and more overdrive in a dirty one. Raising the pickup increases the output and lowering the pickup decreases it.

There are other incremental tonal changes that accompany this adjustment. These can range in intensity between different pickup models, but generally speaking, a pickup will sound brighter and dirtier closer to the strings and rounder, darker, and woodier further away from the strings.

I find also that pickups set lower are more responsive to picking dynamics. Whether this is a product of decreased median output and hence, more headroom, or if the lower pickup position physically provides them with a larger “window” through which can detect finer detail in string velocity, I don’t know. Whatever. It works. Practical knowledge FTW.

Additional Considerations

While 95% of what you need to worry about during pickup adjustment is covered above, there are a few ancillary factors to be mindful of, specifically: clearance, sustain, and pickup-to-pickup balance.

Note the grooves worn into the P-90 housing from string contact

Pickups can be raised up pretty close to the strings without actually making contact while we’re testing out the adjustment, but actual playing conditions do vary and we may find that palm mutes or heavy picking causes the string to choke out some against the pickup. This is decidedly… undesirable. It sounds bad and can cause the strings to wear grooves into the tops of your pickups over time. If this happens, lower that puppy down a hair to get it out of the way.

Passive pickups can also exert a small amount of magnetic pull on electric guitar strings. If the pickup magnet is particularly strong or set too near the strings, it can act as a dampening force on them, reducing sustain, and in extreme cases, actually cause the strings to sound out of tune. The latter is rare, and the former is usually an easy fix, so if you find that your guitar seemed to “sing” more before you adjusted the pickups, try lowering them down a little bit.

The last thing to consider is the output ratio between bridge and neck pickups. This presents something of a balancing act between getting the pickup height just right for each of them so they sound their best individually while keeping their output as complimentary as possible. I find that I prefer a slightly hotter bridge pickup compared to the neck pickup and adjust their height accordingly, but tastes differ on what makes a good ratio between bridge and neck pickup output, so again, trust your ears.

If you haven’t adjusted your pickups using something like the above method, give it a try. I guarantee it will take you less time to do than it’s taken me to write about it!

For those of you who’ve done this many times – could I be missing anything? Do you have any alternative methods? Let us know in the comments.

    I tried the idea of using a audio program so I could see the difference in volume. I think it worked out pretty well, but It was making me a little nuts though because I couldn’t tell if I was plucking each string with the same amount of pressure. I think after messing with it for a while I got it close.

    I remember when I first started playing guitar and came across and article like this in guitar world. At the time it was something I never thought of adjusting, now it’s part of my habit when setting up a guitar. When setting pickup height I generally drive my amp into a distortion beyond what is usable and play a harmonic on the 12th fret of the 6th E string and adjust the height until it stops oscillating, then I repeat with the 1st string. If the poles are adjustable and flat head screws I try to keep them the same height across but keep the pattern of the screws looking like / / / Not sure if it does anything with the magnetic field like the article I read years ago said but the placebo effect is fine for my ears. I’ve never had an issue of one string sounding weaker or stronger than the others this way, (the exception being staggered non adjustable magnets on some single coils) of course the magnet type, string gauge, flatter fret board radius I use, and which direction the sun is facing, may all have something to do with it too.

  • Eric Eikenberry

    I find that, with high gain pickups like the Dimarzio Tone Zone, the Seymour Duncan JB, the Carvin M22SD, and the Jackson J-90C, there’s a range past which you should not go, when raising the overall height of the pickup relative to the strings. Picked notes will have so much “power” that they compress dramatically, flattening the peak on the waveform, and creating a sound which “blats” to my ears. While some with weaker amps will consider this to sound “heavy”, it is a sign that the pickup is too darn close to the strings. Back them away about 3/16ths of an inch, give or take, and all four of those pickups become far more harmonically diverse and rich-sounding. Go too far down and they can be come woody and muddy, particularly the Tone Zone.

    Thanks a lot,pal! But what about single coils pickups?I bet it is the same,but… And more,I’ve read that in order to set the tuning of the strings,You have to pull them on some frets,maybe checking the harmonics,don’t know,because it is the most reliable way to tune correctly a guitar. And last thing, on the bridge,for each string ,there is a little “saddle” (that’s the way we call them in italy) with two little screws each. What are they for?There’s a way to use them correctly?Hope that all these thing are not out of topic.Thanks in advance!

      those screws are for setting the intonation of the bridge saddles. they’re essentially for fine tuning all the frets past the 12th fret.

        Ah no., The intonation screws affect every note on your guitar by changing the length of the string. If your intonation is out, the further up the neck the note you play is, the further out it will be.

      If you are reffering to the little allen screws on the saddle right next to the string that most strat(and many other) bridges have, those are for setting up your strings to follow the radius of your fretboard

      the alen screws are for adjusting the string height, the philips screws that hold the saddles to the bridge are for your intonation, it has nothing to do with fine tuning past the twelth fret, a good intonation will make your guitar sound more in tune all over the fret board

    This may be a personal crusade or simply tilting at windmills due to the huge misuse of this by even some experts, but…the correct term for magnetic or acoustic or any physical attenuation of cyclical energy is “damping.” Not “dampening,” but DAMP-ing. But please know that this is a great article, and you have done a wonderful job of explaining the issue.

        Gary correctly, and very politely, corrected the word usage. He didn’t make fun of the guy, nor did he try to disparage him. You, on the other hand, decided to troll for trouble, and given your luck, you found it.
        Using the incorrect word changes the meaning of the message. If the intent is to get a certain message to readers or listeners, then the use of the proper word is warranted.
        People like you, who get all hot and bothered when grammar is corrected, are likely the one’s who hated to learn their own native tongue and it’s proper usage. In the US we speak a form of English called “American”. No need to get puffy and annoyed when someone politely corrects someone’s grammar. If Gary was being abusive, such as what you’re doing, then he should get called on it.
        Yet, he was not. So your comment is not called for. And, I see some others feel the same as I do.

            I can’t resist; Gerhard is mostly correct, but the word is not limited to everything technical…the device in a stove’s chimney used to control exhaust airflow is also called a “damper,” indicating to me that ANY device that attenuates operation qualifies for this name.

            On a different, but related note, I’m a firm believer that if you’re not learning something new every day, you’re not paying enough attention. So, whether it’s someone very politely correcting someone’s grammar, and the recipient’s polite acknowledgement of said correction, or someone who takes time to put together such a well-written article (albeit with at least one grammatical error) on guitar tech, there is always something to learn that will improve ourselves.

            Thank you, Adam, for composing such an informative article. I enjoyed it, and understood everything without catching the error, or caring much about it once it was pointed out. The important thing is you related the material in a way I found to be entertaining and easily understood.

          Seriously, I thought Todd was just being funny. or like me, trying. He didn’t seem to be all ‘H&B’ Anyways, we all get the big pic & the meaning. I think that all of the pickup adjusting goes hand-in hand with proper & personal action and intonation adjustments, too. The height of the neck pickup in relation to the (end) of the fretboard itself and playability high up the neck with regard to string action height. That then in turn sets the balancing the output of your neck pu height; if slightly hotter – and if that’s is your preference. It does all goes back to the fact that nothing for setup on a guitar can be “perfect”, cause of the instruments’ design its based on small compromises. But it is that small level of imperfection is what lets a players unique individuality come thru.

      I agree Gary. The term is often misused.
      However, the words “damp”, “dampen”, “dampening” have many uses, and the definition is dependent on context.

      A clarification if I may. Physical attenuation of an acoustic guitar’s volume, by stuffing it with something to deaden it’s volume, can correctly be called “dampening”.
      One of the uses of the word “dampening” is to “dull, deaden, restrain, depress”.
      So if one is going to do one of those things to, say, a magnetic field, or acoustic energy, then one can use “dampening”. In that case, physical attenuation can and may be described as having a “dampening” effect.
      Another example would be; Soundproofing a car can have a “dampening” effect on external sounds by effectively decreasing their volume level as heard within the cars cabin.

      In the context of this article the writer is referring to the area of Physics.
      He is describing the effects of a magnetic field on metal guitar strings.
      The word to use in the context of physics, relating to the reduction of vibration/oscillation, is “damping”.

      To muddy the waters further, some would argue with that as well. :)

        And, let me add, the opposite of dampening is drying or wicking away, depending on the context and verbage, which, by the way is a made up word used to make me sound knowledgeable. I hope this clears up the misunderstanding, or should I say, dampens the subject.

          Two questions:

          1. If this is a new guitar, did you remove the plastic film on the pickup covers?

          2. If that was done, did you contact Dean Zelinsky regarding the problem with the StrettaVita? I believe they have a return policy and would be more than willing to help you out rather than have the guitar returned.

          Another item is that the guitar is a Les Paul style guitar so it should be able to do classic metal along the lines of Iommi, however both Yngwie and Blackmore used Strats with single coils so their tones will be slightly out of the ballpark for the StrettaVita.

            I would contact Dean Zelinsky and ask them about it. Also make sure that you have the amp set properly. If you want dirt make sure the gain is up. Don’t be afraid to tweak all of the adjustments all the way in both directions to see exactly how much gain, treble, bass, etc. you have to work with. I would also try raising the bridge pickup all the way up to almost touching the strings and see what difference it makes. You wouldn’t want to leave it there obviously, but just to see if it boosts the output toward what you’re after. If it’s still weak, it may be a bad soldering joint or pot or something in which case they should fix it under warranty.

            I would give them a call and maybe even see if they’ll let you play it over the phone so they can hear it.

    I think players should listen to how strings sound with guitar unplugd. Than, make the desireble djustments. For example, if thiner strings, or any string, sound weaker compared to others, such pick up tunings can be useful to eliminate, minimize or balance whatever bugs ones ears. Or other stuff like setings for rithym and lead. Such adjustments are preaty simple to comprehende and to set. Most of quality gear are needles of such tunnings.

      you should definitely set it up, they can’t set it up from the factory since you might have your strings set higher or lower depending on your tastes, So there is no way of them knowing how to adjust things on their end.

    I have forever been happy with the tones of my Lone Star Strats. SD Pearly Gates Hum in the bridge and single coil Fender Texas Specials, mid and neck. My problem is the Humbucker is so much hotter than the Single Coil neck. It’s a shame I can’t switch between the 2 when soloing. Big overall volume difference. Should a height adjustment help with this issue? Or am I just S.O.L. because of the output differences between the 2 PU’s? Thanks. Very informative article.

      Wonder if lowering the humbucker would help but I definitely understand the HOT pickup.
      Below is my 1985 MIJ Squire Strat that I bought (OK stole) from a friend for $37.50 about 2 years ago. Had the same issues with the HSS configuration and the humbucker output had to be 15K-17K.. Although they are not SD pickups, I had 2 hotrail pickups installed that really balanced out the guitar much better. The neck PU is 6.5K and the middle PU is 10K. The guitar tech I’ve used for over 25 years said he really liked them and that they retained some of the single coil sound but definitely were able to push them. Unlike a lot of Strat pickups and configurations, this middle pickup actually sounds really good in 3 position.
      Good luck. .

  • Mark Markguyver Gibbons

    A good overall article, except… It seems to me setting individual string height and THEN setting pickup height is completely backwards. Having a roughed-out even tone between pickups and across on the high and low “E”‘s, then setting individual string strengths seems far more logical.
    Say you set the strings individually, then find that for proper output, the p/u has to have a bit of “tilt” (higher on the high “E” side usually). All the adjustments you just did need to be redone! I say, rough set with p/u height, balance between p/u output, THEN set individual strings.

    Mark Markguyver Gibbons did not rate this post.
    • SeymourDuncanBlog

      You set the individual strings first to establish balanced output across the strings, and then adjust the overall pickup height to fine-tune the overall output. Doing it in reverse makes it harder to find the overall output you’re looking for because you aren’t hearing all the strings at a balanced volume.

      A pickup that is fully covered – I’m assuming you’re talking about one that doesn’t have a row of screws poking through? There is no individual pole adjustment for those kinds of pickups. Most often they either have two rows of non-adjustable slug poles or are active pickups constructed via a totally different method.

    I actually posted something about this. You did kind of miss something if I have nickel plated humbucker like on a Les Paul when I turn the screw to the right and and the screw goes down lower is that making the magnet on the other side higher? Or by turning the screw to the left is that making the magnet higher? or are the screws the actual magnets?

    Adam gissin did not rate this post.
    • SeymourDuncanBlog

      The answer is “no” to all of the above. It’s not a see-saw. Lowering an adjustable pole piece isn’t going to affect the position of the rest.

      In a traditional humbucker, covered or not, the pole pieces are ferrous metal but not magnets themselves. The magnet is a single bar magnet positioned under the bobbin, between the bobbin and baseplate. It rests in the middle, running from end to end, between the 2 rows of pole pieces.

        The major problem is that the bobbins are adjusted for even peak volume. The plain strings have a much larger peak volume compared to the sustained volume, so when adjusted this way the plain strings will always sound lower in volume.

    Attenuate could be used as well, ie. ‘undesirable attenuation’ ; It works well to follow the radius of the string lie and 1. tweak G string if necessary 2.set neck lower to accomodate strings vibrational arc.

    Clear article! I was wondering about wich way the sides with the screws go, i see different setups.

    Screws outside, furthest from each other [: ] [ :] that i see the most.

    Both pickups’ screws closer to the bridge, [: ] [: ]

    Both closer to the neck [ :] [ :]

    Or closest to each other [ :] [: ]

    I hope u understand what i mean

    I know different positions make different timbres, and i wonder is there a best way?

    Or is it all in the ear of the guitarist, whatever he or she fancies?

    Do i need to take special precautions, whit soldering them in or is there no such thing as in or out of phase, with various positions?

    Thanks a lot!

    • mrelwood

      Good question! Generally, the pickup sounds slightly warmer and fatter when the adjustable polepieces are closer to the neck. But the orientation becomes very relevant if your pickup has two different sounding coils (several DiMarzios for example), or especially when splitting a pickup.

      1) When split, the coil without adjustments will always have a bad string balance, so it’s usually best to have the adjustable coil as the active one. Also, the position matters quite a bit, so if you’re after a Strat/Tele pickup sound, be sure that the active coil is closer to the neck on both bridge and neck pickups.

      2) A humbucker with different sounding coils (for example DiMarzio Bluesbucker) can sound very different when rotated . Here also, often the adjustable coil towards neck yields a warmer and thicker sound. If both coils are adjustable, you should find out how that individual pickup behaves. DiMarzio Steve’s Special for example has a warmer sound when the cable exits the pickup closer to the neck.

      I always have the neck pickup screws towards the neck for a great split sound. I do have my bridge pickups both ways though; both humbuckers split to the furthest coils has a cool Telecaster-like sound. And the rear coil alone is great with higher overdrive, makes for a very distinct difference when split vs humbucker. But for milder overdrive and a Strat-like bridge pickup sound, the front coil is better. Also, the front coil sounds better together with a middle single coil.

      mrelwood did not rate this post.
      • mrelwood

        The orientation of the pickup doesn’t affect the phase or polarity. Out-of-phase is done with the wiring, so you can try different orientations without even opening the control cavity.

        When soldering the wires, you just have to know which are + and -. But when splitting, you have to know those for both coils in order to get the coil you want. Easy fix though: if the humbucker splits to a wrong coil, just make the coil splitting switch take the coils’ connection wire (the two wires that are connected together) to the pickup’s + instead of ground. Or vice versa.

  • Six_String_Fling

    I can’t believe no one has mentioned that the higher the screw is, the more clear, and trebley (not real trebley, but somewhat more so) that string will sound. The opposite is true with lowering the screw(s). So if you can’t get your pup high enough because you get the ‘woofing’ sound, or clicky picking sound, lower the pup a tad bit and then raise the screws in the same amount you just lowered it. Then viola, you will get about the same output without the ‘woofing’ sound. You might even be able to go a little higher with raising the screw. You just have to tweak until you get what sound you want. It is there, you just have to find it.

    Six_String_Fling did not rate this post.
    • SeymourDuncanBlog

      This is true. Generally, the further above the bobbin you raise the pole, the brighter the string above that pole will sound. I considered this secondary to adjusting string-to-string volume, however, as using the poles to adjust the brightness of individual strings can result in a pickup that sounds very uneven in volume across the strings. Especially if you’re new to making these sorts of adjustments, as are the folks this article is aimed at.

      • Six_String_Fling

        True, that’s why I specifically stated “lower the pup a tad bit and then raise the screws in the same amount you just lowered it ” and that “You just have to tweak until you get what sound you want.” Finding good tone takes some time, but you got to start sometime if you want to learn. Nothing teaches you better than the mistakes you make. So I suggest to the newbies go test it to see what you like, set them every which way you can and listen, and hope you mess up. This way you can learn. And, hey, if you get lost just lower everything back flush and start all over. If you take measurements along the way, and write down what sounds good, you may not have to go back as far as you think!

  • jimsreynolds

    Good article and great to see this kind of knowledge out in the wild! Wanted to throw in a couple of things, from my own experiences:

    1) The strings move (oscillate) more above the neck pickup than they do the bridge pickup. This makes for more volume naturally at the neck pickup. To balance neck and bridge evenly, you must sometimes drop the neck pickup a little lower than the bridge … even more so if you want the bridge louder. This effect is partly negated by the output differences between neck and bridge pickups but is worth being aware of.

    2) While trying to balance off your levels, use a channel on your amp that is clean (and/or adjust the gain) but just starting to break up. That way, it is easier to hear which strings are louder …. they distort more. Also, when you strum a chord (slowly) you can hear more clearly when the whole chord is balanced.

    3) Personally, I prefer to adjust the pickup height first before the screws. I set the overall brightness/compression of the pickup before I level off the strings. Personally, I tend to prefer the pickups back off a little these days to improve the dynamics. Also, on some pickups (e.g. P90s) the pole piece adjustments can make quite a big difference when the pickup height is in the ‘sweet spot’. Just my preference but worth considering.

    4) I do this on all guitars with adjustment but the ones that really love it are the ones with P90s. A balanced P90 set a little lower than typical is a thing of beauty. It completely changed the way I felt about a Les Paul Jr-type I had with them – from a thrashy munter to quite the tone monster.

    Essay out !

  • Skyline UK

    I play mostly lead guitar and find I always have to heighten the screw poles of the top two strings (E, B), otherwise when playing a phrase that goes onto those strings from the others I feel a slight drop in volume which I hate. My excellent guitar tech adjusts them to be all equal (with a decibel metre) but I find equal isn’t right for me! It could be something to do with hearing loss over the years, but I don’t think so. Strats are a nightmare for this – they all seem (to me) to have a massive drop off in volume on the top two strings, and oddly the non-adjustable poles on a Strat are usually factory set LOWER for some reason. Ah, the mysteries of life eh……!

      Good point – there are lots of reasons why what is even on the meter might sound different to your ears when you are actually wailing away. A big one is your touch, which will be different than anyone else. The meter is a good start (and using the computer or phone app is brilliant – hadn’t thought of that but we all have a phone/tablet/laptop with us almost all the time).
