I noticed that there was a mix pot used on Ezra's custom guitar.  I would like to know how that circuit is setup.  Are both at 50% output or 100% when in the center? At full left is it A=100%, B=0%; center A=100%,B=100%; full right A=0%, B=100%?

If I remember correctly, it's normally 70% and 70% at center detent, and 100% at either far end.

Thought this thread was going to be about something else!
