I fixed a P-Bass the other day which had been badly mistreated (it's a Johnson I bought for $30 -see my other thread about the Dragonfire pups). It was wired in an odd manner, with the capacitor soldered from the pole of one pot to the neutral of the other... When wired this way, the two pots controlled the volume and the sound was weak. My guess is that the previous owner screwed around with it (as he did with other parts of the bass). I used Martin Koch's book and rewired according to his schematic, now the pickups works perfectly, one pot as volume (and it seems to be a log pot, which I was not sure), the other as tone (and it seems to be a straight pot, which I was not sure either, apparently I was lucky). But when I look online, I find that there is indeed a way to wire the P Bass with the capacitor between the two pots. That does not seem right, because when I drew the schematic it did not look like it would work properly... And indeed it did not. So how there is more than one published way to wire a P? Thanks!
