Lightbulb Does anyone make a blend pot like this?

This seems to me the ideal blend pot.

oops, it's linear.

I will take this opportunity to make a very stupid question..

When You pan all the way to a Pickup, it works at its maximum potential/volume/output?? as would happen when there are basses with a individual volume pot for each pickup??

I can't imagine wanting it the way the OP lists. Basically the only way to hear full volume on one pup is to have the other one completely off.

Put that graph upside-down and then it'd work for me.

Oh I'd mistaken resistance to conductance. Looked like it was sending it all to ground. Nevermind.

Stewmac's seems the way to go, regardless.

Are there any 6 pin blend pots that aren't like Stewmac's?

I'll try to give a workable answer.

The pots take input on the middle wiper, and then balance between putting the signal to the output vs ground.

(Or you can put the input to one of the side lugs and take the output from the middle wiper)

At one end of the turn, it sends all the signal to ground, completely silent. As the resistance to ground goes up, more signal is passed to the output.

The blend knobs at Stewmac (and I think most everywhere else) are set up to be full volume both pickups at center detent. As you go further from the center, it sends more to ground of one pickup while keeping the other full on.

you don't want audio taper curves like that, though. typical "M/N" blend pots tend to jump too fast from "both full up" to "one by itself" even with linear tapers as it is.

if anything, a "reverse audio" m-n pot, where a pickup only gradually began to be turned down when the knob was moved might be the best way.

That's the kinda curve I'm looking for, except I want audio taper on either side. We're talking about volume, which to our ears is logarithmic. It makes no sense to use a linear taper. That's why there's virtually no change in sound through most of the knob travel with MN (linear) taper blend pots. Perhaps it's not so bad with 250k pots, but with 500k pots you may as well just use a 3-way switch.
