Coil arithmetic
Aside from hum canceling, would a coil the size of 2 humbucker bobbins (think of 2 bobbins glued together, side-by-side) be similar in tone, output, etc to a "standard" 2 coil humbucker, assuming the same materials, total DC resistance, etc?
Or to put it another way, what would one big coil the size of 2 HB coils sound like?
Re: Coil arithmetic
Too much psycho-physics embedded in this question for a reasonable Friday afternoon answer . . . . however, consider this: two humbucker coils lie relatively equidistant from the pole of a bar magnet.
One big coil has one half of the coil twice as far from the magnet as the other.
Thats one factor. I'll leave the rest to others.
Re: Coil arithmetic
A P-90 is a pretty fat single coil. It seems to be in between a SC and a HB. Fatter than a SC but thinner than a HB. I don't know of anything closer than that.
Re: Coil arithmetic
Someone needs to make a humbucker sized single. That would be great... something wound to 40K.
Re: Coil arithmetic
To put this in perspective, my SSL-3 is wound to 16.5k and my AII Pro is wound to 7.8k. The single sounds like a single and the humbucker sounds like a humbucker. Go figure.
Edit: And don't forget . . . this is the logic of Friday night.

But what if you literally took 2 HB bobbins and glued them together:Originally Posted by ArtieToo

Wind one big coil and use 2 sets of poles in the same format as a HB. The entire coil would be equidistant to one of the magnetic pole sets
Food for weekend thought. Hmmm...
Re: Coil arithmetic
My guess is sth in between but closer to a P-90 than to a Humbucker.
With the humbucker everything makes the tone, including the RW part of the two coils etc.
If we really want hands-on data then the all-new P-Rails will be ideal.
IIRC Frank said they designed it around a P-90 so if in series it sounds just like any other humbucker then, maybe; but if it sounds as sth different, even slightly then chances are that what you say would sound even less of...
Re: Coil arithmetic
You cannot do that without throwing either resistance, capacitance or inductivity totally off and then your EQ is all over the palace.
Re: Coil arithmetic
Help me understand why; because of the size of the coil?
Re: Coil arithmetic
Right. If you just take the normal number of winds and resistance and spread it over more space then the capacity should go down. Not sure what that does for inductivity. And you can't keep number of resistance and winds in the first place since each wind is longer. Maybe if you use awg 41 or something.
Then there is a big problem with the magnet. You cannot use the normal humbucker configuration with a magnet at the bottom and then one set of north and one set of south poles go up. If you put a single coil around them they would cancel each other out.
So you are stuck with one magnet with north or south up.
But once you only have one magnet you have the problem of size of magnetic field. Your coil must live in the field, but now only a tiny space inside your large coil has a magnet. So I guess you would have to take a much large magnet of weaker strength. Or have one set of Strat style pole piece magnets with two sets of passive poles next to it.
Overall the magnet problem leads the whole project back towards the P-90 direction and a P-90 sized coil.
