UPS is bringing me a '62 RI Jazz, and it has the stacked pot configuration. I've never cared for that configuration, and I'm going to replace it with the three pot setup. Here are my questions... The stacked knobs use 500K for volume and 250K for tone. Given how jazz pots are wired together, does that mean that if each volume pot is 500K, each pickup acts like it's wired to a 250K pot? And if each pot is 250K, that each pickup acts like it's wired to a 125K pot? Second, I want to put a push/pull switch knob for series/parallel switching on the tone pot. Does anyone have a source for a 250K audio taper solid shaft .250 pot (preferably CTS) with a push/pull pot? I've found split shaft versions, but not solid, though I've found one desgned for use in amps that might work, though I need to get the dimensions.
