ok, my volume pot on my thumb is darn near going out. so i'm going to rewire it passive until i have the cake for a u-retro. it has active pickups, and i'd want it to be volume, blend, tone. (so i'm going to follow EMG wiring diagrams) unless volume volume tone is drastically better tone wise i'd much rather have the blend because which pots do i need? i want the BEST tone possible out of this rig. it's been so long since i've played a passive bass - is there a way that i can get a bass boost? like, having twin tone controls perhaps with different settings? what about push-pull for parallel/series? is that possible? or should i just keep it simple? please - someone point me in the right direction. i have no clue what i should be looking for in terms of pots.
