Double Pots?

[saiyuki]

Hi all. Something i would like on my MM Sabre2 is double pots, but am not aware that such an item exists. I have the standard 1 volume, 1 treble, and 1 bass pots, but as you all know whatever the tone controls are set at for e'g the neck pickup, the bridge pickup uses the same setting when switched to that pickup.

There are times when i switch pickups and need to adjust the tone, and this is not desirable as it breaks the continuity of playing.

Therefore is it possible to have push/pull double pot switches that can be individually set for each pickup? Outwardly the guitar would look the same but with the capability of seperate pickup tone controls.

Regards

Yes- you can install what's called a "dual concentric pot". It's two pots in a single package and would accomplish what you're after.

Many thanks for the info.

interesting concept!

Yes beej is correct, I used 'dual concentric' pots on one of my AL HH's to achieve the desired effect that you are looking for. It is now wired with separate tone and volume controls for each pick-up very much like a LP... Works great and sounds fantastic, and i did not need to alter the pickguard.

Hi. My Sabre2 has an active circuitry with the pre-amp located on top of the tone pots. After the encouraging info from members here, i have also thought about doing the same with the Volume pot. Because of the high output of the pickups i find at halfway the volume is clean, increasing up to full invariably overloads the amp. Therefore i would like to have a push/pull volume pot which can be 'normal' range in one position, and upto half the other position -sorry if i can't explain that better.

The Volume pot is a 25K-A, the treble pot is a 1M-L pot and the Bass is a 100-K pot. I can't seem to locate a suitable 1M-L pot. I'll probably get a more experianced person to do the work, but i would like to purchase the required components myself so i know good quality grade parts are being used.

Hi there,

There would be a problem with only using double pots: the pots are used as a part in the circuit of the preamp. You can not just hook up the two pots to the same circuit, they would interfere... Basically, you would need two complete pre-amp sets, each connected to one set of pots to get this to work, OR make some kind of switch to select (electrically replace) one pot-connection with the other...

But I like the concept...

Cheers, Joep

I'm not familiar with that preamp, but a work-around would be to switch each pot in/out with the pickup selector. (Might replacing it with a multipole switch.)

Hi. Here's a diagram of the circuit that i have. Not being electronically minded... What if a push/pull double ganged pot was used. If the wires were connected to both pots the same way, and they were operated on a push/pull basis, would they interfere then as only one pot is used at any one time?

Regards



[EDIT] - @vandePut... It's hard being Dysloxic. What you said about "You can not just hook up the two pots to the same circuit" has just kicked in. Please disregard most of what i said above. Lol

Note to self... Make sure thinking head is on.

 

[beej]

So you could replace the lever switch with a 4 pole lever switch (megaswitch, etc.) and switch the active pot in or out. There might some some clicking as you do this, you would have to experiment somewhat.

Bigger issue is that it might be tough to find a 1 Meg Dual Concentric pot.

So this will probably end up being a whole thing. But good luck!

Does anyone have a wiring diagram for changing the AL HH single volume pot to a dual-concentric pot (So that we would have independent vol. control for each pickup, as described above)?

That would be fantastic!
