Blend pot for OOP?

[jtgreen]

Is it possible to wire a blend pot for phase switching? So far, I have found no info on the subject aside from using push/pull pots and switches. Could there be any usable sounds between in phase and out, or is that impossible?

Pretty sure you could just wire the six lugs of the blend pot exactly like the six lugs of the DPDT switch that's typically used. It'll probably act like a funky volume control, with severe attenuation (and I'd guess a good deal of noise) in the middle of the rotation.

jt,

Hi, and welcome to the NutzHouse! ;D


Short answer is: no, can't be done.

Reason is, your looking at phase relationships between two pickups. If you have two separate '+' signals going to the pickup selector switch, you can elect to reverse one of them for an OoP sound. However, you want to "blend" them. That's asking for part of the '+' signal and part of the '-' signal each to appear at the same point, presumably the common point on the selector switch.

Well, I don't know about anyone else, but when I have a '+' and a '-' signal from the same source (pickup) at the same point in a circuit, I tend to call that a short-circuit. You can't blend away a short, sorry to have to tell you.

ash's comment above is correct in that you would have a dead spot on the control, and in either direction from that point, there will be either full in-phase, or full OoP.... probably at a reduced volume, which will seem to increase the noise factor.

However, not to pee in your Cheerios too deeply, you might consider the HOoP, or "half out of phase" option. That can be controlled by a switch or a pot, your choice. Start with this thread for more info.

I had a feeling that polarity could not be blended, thank you for your responses.
Realizing now I have a few extra parts I didn't need to buy, but it was worth the learning experience. Again, ty for sharing your knowledge.
