Hi, I have a J-bass (with split coil Nordstrand's) on which I never use the bridge pup, so this evening in an experimental mood I rewired the pickups in series just to hear what it sounds like. I didn't use any push pull switches but just used a P-bass schematic for Volume/Tone controls and wired the pickups in series with each other (hot of neck pup to ground of bridge pup). The result was quite pleasing I must say, but the tone control didn't seem to do that much. Some difference in tone was noticable, but it stayed on the bassy/ darkish sound. I then switched the 0.047 cap for a 0.022 i had lying around and the sound did get brighter, but now hardly any change can be heard when turning the tone pot. So now my questions: Is this due to using 250K pots while the 2 pickups where both already humbuckers (2 split coil Nordstrands)? If yes, should I switch to 500K pot's? Or is using a P-bass wiring schematic wrong? And finally, how do I get a tone control in there with some more variety? Thanks!
