Liberator - Grounding | Silencing | Wiring Diagram

[seansiva]

After watching the Liberator video pt. 3 and looking the below wiring diagram that suits to my guitar:

http://www.seymourduncan.com/support..._1v1t_LBVOL_pp

Frank said there is the 4th redundant Ground that can be used for Tremolo cavity ground. From the schematic, I saw there are plenty of "GND" on the potentiometer as well.

Does this "GND" function the same as that redundant Ground ?. The grounding here means removing the guitar noise, like silencing it, am I right ?.

There are some pictures on the web showing their guitar's cavity being sprayed/ covered with copper foils to have a much more silent guitar. Some even solder a shielded wire to the guitar's back panel which has been covered with copper/aluminium foil tape to achieve a much more quiet guitar. So can I use this "GND" for silencing purposes ?.

Sorry if I had a misunderstanding or a total wrong concept here. I'm just curious. Hope some of you could share your thoughts.


So back to the wiring diagram:

"Solder all Green and Bare wires together and insulate."

This means these wires goes nowhere, just do as instructed, maybe then roll and leave it in the cavity ?.


Thanks in advance...

A ground is a ground for the most part. By redundant I think he just means there is a ground on the green connector itself and the grounding surfaces on the top of the pot (cicuit board). Depending on which wires are not grounded you will either have NO sound or noise. You need to make sure the proper wires are all grounded and that you have no ground loops. A ground loop can be caused when there are two paths to ground and may also create noise.

You can shield the interior of the cavities to reduce interference (noise). Humbuckers usually do not need this, single coil guitars benefit more from this. It really just depends if you are getting noise and what is causing it to occur. My Les Pauls do not need shielding but my Strats and Ibanez do.

To answer the green and bare wire question we will need to know what pickup you are installing. If I remember correctly green and bare on SD's go to ground. In fact most bare (if not all) go to ground.

It would be best if you posted the schematic you are wanting to use, the brand and model of pickups that you are going to install, what kind of switch(es), and the make and model of the guitar.

My guitar (ESP LTD M-200 FM)
Wood: Agathis
Fretboard:Rosewood
2 Humbucker(Stock)
1 Volume
1 Tone Control(Push/Pull Coil Tap)
3 way pickup selector
Floyd-Rose Licensed Trem Bridge

I'm gonna purchase SD's TB-6(bridge) and Liberator. I have asked the forum and haven't decide which pickup for the neck here:

So I believe this is the schematic that suits the most:

well explained mate, tx. I guess the wiring diagram that I picked above should be the correct one then...my curiosity is still about what Frank said "there is the 4th redundant Ground that can be used for Tremolo cavity ground".

When I open my tremolo cavity i see no wiring there, so grounding this means soldering a wire at any part of the tremolo within the cavity to the top of the green connector ?. . It sounds kinda LOL but,

Have a look at this video, see what this guy did to remove the noise from his guitar...

Could this what Frank meant actually ?. The alternative to removing the panel itself<Still thinking..uhmmm>

[Fly_with_v]

I believe Frank is just talking about grounding the tremolo. Some guitars do not have this wire or it has been removed. Personnaly i always ground my temolos and fixed bridge just to remove it from being an issue.

I have never grounded the cavity cover. The only noise I ever have is from single coils. But if you have noise try it, it can not hurt, unless you create a ground loop.

Regarding the ground on the Liberator. Now that I have installed one I understand it a little better. You can use the ground pads for any ground. You can have one ground wire going to each or all ground wires going to one, whatever is easiest for you. You can also use the bare and green wire conections. I choose a one to one relationship becuase it allows me to unsolder a connection if needed without disturbing the others.

What I suggest is that you determine your optimal wiring setup first and buy all the neccessary parts. I wanted coil splits on the guitar I just wired. I wired the wires on the liberator as if the were regular pickup wires based on the appropriate Seymours diagram. Then I just install the pickup in the connector to match the appropriate color. If the pickups are SD's you just match Color to Color, if the pickup are Dimarzio, Gibson, etc I just compare each color code chart and intall in that manner.

My next guitar I am doing will have push/pulls with series/parallel/splits. I will add the liberator wiring the liberator wires just like I would if they were the pickup wires. Then if I change pickup I will just need to match the colors correctly and any pickups I put in will have those capabilities.

Once I have all of my guitars done, I will be able to swap pickups from one guitar to the other in minutes to see were I like the pickups the best. If I get a new guitar, I will install the liberator and then I can easily switch my other guitars pickups into the new one to determine what I want in the new guitar. This will save alot of "what type of pickup in my new ????" questions for me. By trying my current inventory of pickups I will understand better how the guitar is responding in a bout 1/4 of the time it would take with the soldering method. I am sold on these after just one.

It so easy, even a caveman could do it.

thanks mate...good info.!...

I really shouldn't have said "redundant ground" because really its redundant to the third lug of the potentiometer. On the PCB I specifically chose only one trace connecting those two to ground. After this thing has been out there awhile we'll do videos of some trick wiring, including one where you cut the trace between the pot's ground (the two "ground" terminals) and the rest of the board's ground so then they're "redundant" pot lug connections. This is also something you'd have to do if you wanted to make it a "Lefty" pot.

[Fly_with_v]

Frank. This is a very good product. Thank you for your work on this. Are there any plans to market it to guitar manufactures as a standard installed product?

[frankfalbo]

Yes but it raises their cost, so it is a tough sell. We're doing what we can and you will see it in a few small pockets within 6 months or so. Then it will be up to the buying public to make it known that it's worth it, just like TonePros hardware, Gotoh, Schaller, or Grover buttons, etc.

[seansiva]

With no doubt, its worth every penny and it will make its name in the market. By the way, I've checked at Seymour Duncan's authorized dealer here, and they don't seem to have the 2011 products. No Liberator, no Blackout Modular Preamp. When will these products reach here ?.

[Dirtbagg]

I got mine mounted to a pickguard for a strat with 2 vol and one tone. going to finish putting it in this weekend.

a very cool product
