petetexas Posted October 8, 2015 Share Posted October 8, 2015 Hi , Has anyone tried changing the 250K Vol and Tone pots in a Precision Bass to 500K and increasing the cap to 0.1mf ? I saw this somewhere , it said that it increased the treble , hence the larger cap . Pete Quote Link to comment Share on other sites More sharing options...

iiipopes Posted October 17, 2015 Share Posted October 17, 2015 The larger value potentiometer on the volume control will provide less loading to the circuit, which results in a marginally raised resonant peak, which we perceive as "brighter." And it does function the same to a lesser degree on the tone control. BUT...increasing the tone capacitor value only lowers the cutoff frequency. It does not "compensate" for anything. All it does is make more mud. In a typical passive tone circuit, using a 250kohm pot with a standard tone cap will be the same as using a 500 kohm audio taper pot with the control turned down to the same resistance, which is about "8" on the knob.

petetexas Posted October 17, 2015 Author Share Posted October 17, 2015 Thanks guys . Quite happy with 250K and .047 for now ( have put a Dimarzio in her ) , when I roll the volume slightly back , it thins the sound out a little ....perfect !
