So I've done a little homework, (just enough to be dangerous), and I got ambitious with rewiring this bass. I never did switch to audio taper -they were in fact linear to start with, but I don't think that's the issue.
I put in a 3 band pre, active/passive bypass, and Series/parallel switch. Here's the diagram:
the bypass and series/parallel switches work fine, as does the preamp. I buzzed the ground through the pre and it's continuous, so I ran the ground from the s/p through the pre to the output, and it works. The pots are grounded to the case of the bypass/tone switch and out to sleeve from there.
- The volumes still cut out at the bottom of their throw, not as severely as before though
- The majority of the volume increase is in the top end of the throw
- With either volume all the way up, the tone does nothing
- The tone control has more effect on the sound the lower the volume is
These pickups are listed as High Impedance, so they shouldn't take really low value pots right? -They were wired to 500k's to start with.
I've also seen diagrams where the cap on the tone is wired from the wiper terminal to the ground and the signal is on the output terminal instead of the way I have it wired, which I thought was standard. Would rewiring the tone make a difference?
I also didn't bridge the ground terminal on the bridge volume to its respective pot. Could that cause problems?
