Stacked tone/blend pot?

[Boston Joe]

Does anyone make a stacked pot that has a regular volume/tone control on one, and a blend pot on the other?

A pot is just a variable resistor until you wire it up to be either a tone pot or a volume pot.

A blend pot is basically to pots mounted to one shaft.

The problem that I fore see in that is that if you did wire one pot as a tone and the other as a volume, you could end up turning the tone up or down while you are turning the volume pot up or down.

A dual concentric pot may be more useful to you.  2 pots, 2 shafts (one is center, one is ring) but you essentially have two variable resistors that take up one control hole.

You'd need a triple-gang, dual concentric pot,like this:

The pic is from Omeg in the UK, so such things do exist. You're probably in special order territory though and might need to order 20+. Good luck fitting it in a guitar cavity too!

Let's wire it up

Thanks. I'm just kind of exploring ideas, so, you know, nothing too serious going on.

I worked in electronics for like 16 years, and I never saw one on those! Triple gang, dual shaft. Opens up a whole world of possibilities.........  :icon_scratch:

What would really be awesome is one where you could pull the knob up and adjust one pot, then push it down and adjust the other. Dual shaft, but single knob.

with different value pots?  with a push pull switch?  I think we're getting into serious custom order territory here!!  but - totally doable

I probably wouldn't order such a thing. There's a limit to what I'm willing to spend on a pot, even if it's really, REALLY cool. It would be easier just to add another knob.

But yeah, Let's say you have something like that, so you pull the knob up and adjust the blend between the two pickups, then you push it down and set the tone. Ideally, they would be completely separate. So when the knob is in the up position, it only rotates the sweeper on the blend pot, and when it's in the down position, it only rotates the tone. The way I was thinking about it, the blend pot would only be in the circuit if you're in a two-pickup position on the selector switch (I.e., the middle position on a LP or Tele).

But the whole point of having a Blend - as you find on basses - is so that it eliminates the toggle switch. Having both seems redundant to me. Turn the blend one way and you have the first pickup. Turn it the other and you have the other pickup. Leave it in the middle and you have both. Just like a toggle, but with a gradual change.

 

[stratamania]

Boston Joe, do you have some other definition of blend pot, as to only use it on a two pickup guitar when both are on you have nothing left to blend?

Some wiring schemes for Strats, for example, have one volume and one tone, and the third pot is then used as a blend pot to blend in when in the bridge position some neck pickup into the signal.

It'd be just another level of tweakability. For any given blend of the two pups, you'd also be able to adjust the overall tone. It's just a wacky idea. I really just figured I'd say, "Does this exist?" and someone would say "no" and that'd be that.

I really like the idea of hidden functions on a guitar. Something that looks really simple, but has a multitude of functions.

When the two are on with the selector switch, they're on, and whatever ratio that gives you (50/50, I assume) is what you get. And sometimes that'd be the sound you'd want. But other times maybe you want 90% neck pickup with just a touch of bridge, or vice versa.

When the two are on with the selector switch, they're on, and whatever ratio that gives you (50/50, I assume) is what you get. And sometimes that'd be the sound you'd want. But other times maybe you want 90% neck pickup with just a touch of bridge, or vice versa.

Then it that case what would achieve that is no selector switch, like on a bass. No blend pot, but two volumes used to blend.

Here is a link to a diagram.

The same sort of idea works with Jazz Bass wiring where one of the volume pots has a concentric pot for master tone. Either way, the blend is done by the combination of individual pickup volume.

Sure, Captain Buzzkill, that would work. But where's the neato factor?

(I hope that's taken in the spirit I meant it.)

Sure no worries...
