Concentric/Stack knob

thisSNsucks · #1 03-05-2007, 04:14 PM

I want to outfit my Mark Hoppus Bass with a tone control but dont want to have to drill a new hold in the pickguard. I want to put in a Concentric stack knob right were the single volume pot sits now.

Right now I can only find 500/250kpots. I know when you wire a standard P-bass you use both 250k pots.

Anyway, do any of you know where to find a 250/250k stack pot? They have to exist. If I end up using the 500/250k pot, I'll have more high end correct? Thanks!

though you really can use higher. no law against it. i'll be using 1meg pots in my next project to see if it makes a difference...

That link is for a 250K/500K pot....I would just use that one if I were you+ make the 500K part the tone- a 250K tone will roll off more treble even when it is all the way up, while a 500K can do everything the 250K can do and more...

If you really want a 250K/250K, you can buy one of the above pots and a 250K pot (from the same manufacturer!) + take them apart and put the carbon ring portion of the 250K pot in place of the 500K portion...nobody makes a cheap 250K/250K stacked pot for some reason.

Wow- I've never seen those before, that's good to know...Last time I looked for one I could only find custom made ones that costed $50 apiece! Luckily I have a ridiculous parts drawer with plenty CTS pots to gut and recombine...

I have one of those drawers too - but I can't very well sell new basses with reconstructed parts.
