Volume pot values?

[Alun]

Hello all. The volume pot on my Curbow is starting to play up so I'm looking at replacing it. According to the Cort schematic it's an audio taper pot rated at 25k ( it's a Bartolini Ml1 humbucker with a Fishman active preamp). My question to you infinitely-wiser-than-me folk is - what difference would a different value pot make?

The reason I ask is that I'm struggling to find a mini 25k pot but there are 250k ones everywhere.

Thanks,
Alun

If it's an active bass with a preamp and a battery then 25k will be the correct value. You can't replace it with 250k as this wouldn't work right with the electronics.

What kind of shaft do you need on the pots ? Splined or solid ?

Thanks Bod. Any idea what the effect would actually be? I'm assuming the "k" is the pot's resistance but I don't have a lot ( if any!) elctrical knowledge so am curious to see know what the difference would be.

I've never tried this with pot values that are so different. It would most likely not work at all, be full on all the time, or have all the pot volume variation limited to a fraction of a turn of the knob - so the pot would act more like an on/off switch.

Ah, thanks Bod.
