I have installed an older active Bartolini P/J set in my fretless (thanks to Irvine here for the swap). It is working perfectly and sounds amazing, functions as I expect it to so I am sure the wiring is correct. It is wired blend, vol, tone - no "preamp" or mid cut/boost controls.
- 100pF cap across neck pickup for brightest tone apparently - the Bartolini diagrams show a "Vintage Tone" option of a 68K resistor in parallel with a 0.001uF cap
- 0.1uF cap between vol and tone pots
- 0.033uF + 1K resistor from black pickup wires (this is probably irrelevant)
I have a 0.047uF cap on standby, but as I understand it this would be less dark than the 0.1uF. I don't want to employ the "Vintage Tone" option on the neck pickup because I want to keep its modern sound.
Could this be as simple as swapping the 0.1 with something even larger, or should I have another cap (0.047?) across tone pot leg and ground as well, as is usually the setup? Should I only have a cap across tone pot leg and ground instead of between vol and tone pots?
There's no space for switches or push-pull pots. I am sticking with round-wound strings.
Insights greatly appreciated, thanks!
