VOL/TONE/PU SELECTOR SWITCH WIRING - CONTROL POT VALUES?
Hey - I'm going to mod a jazz bass for vol/tone/pu selector switch. There are lots of good threads on wiring, but - I have this question -
What values should I use for the vol and tone pots? Assuming a std jazz bass, that has 250k pots - should I use the same 250k pots?
It seems like I should use other values for the pots, because of the circuit change from vol/vol/tone to vol/tone/switch.
My goal is to have the tone of the bass as close to the original wiring as possible.
Is there a math formula for this? Or? THANKS!
PS - here are a couple of threads on the circuit - http://www.talkbass.com/forum/f38/wi...bridge-768494/
Pots are a personal preference, and account for only a subtle tonal difference. Use whatever sounds most appealing to you. Higher values are brighter, lower values are warmer.
To be technical, the load from the volume pots in a VVT setup with 250k pots is 125k. With only one volume pot, there is no common value equivalent to this, but a 250k pot with a 220k resistor parallel to it is about the same.
