The short story: I've found (with my ears and bass at least) that if one pickup is louder than the other (blend pot or VVT) then the quieter pickup is essentially at zero no matter what it's setting is. IE: I perceive no tone difference when say; the Bridge = 100%/Neck = 70% to when the Bridge = 100%/Neck = 0%. The long story: I'm a big fan of modding guitars/basses, especially the wiring of them. I was thinking about putting a blend or pickup pan pot on my Jazz bass. I thought I'd try out a rudimentary DIY approach before I put any money down for the component. I did this by maxing one pot and zeroing another then putting a rubber band around both with a twist in it's middle. So by tuning up one PU you are turning down another. Turning one dial to 50% sets both pickups to the same volume, identical to some (not all) blend pots. However I found that anything away from the 50% mark where both PUs are at the same volume it essentially turns off the PU that is being turned down. I double checked this by removing the rubber band and maxing a single PU and killing another. Then by plucking a string and slowly turning up the PU that was at zero, and listening for a difference in tone. I found that (to me at least) there was no audible difference in tone at all until both PU are maxed (or at the same volume) and thus in parallel. Of course if you kill both pickups and pluck a string and turn one PU up then there is an obvious volume swell, but when one pickup is maxed and you swell the other from zero there's nothing till it's 100%. So my questions are: Has anybody else found this? If so: why does this happen? Ps: I'm assuming with an active system that this is not an issue at all.
