I am putting together a project bass. The pickups are passive, and i want to know where one can find the pots and cap for the controls. Radio Shack was no help. I got a schematic from seymoreduncan.com that requires 3 250K pots and a .05mfd cap

Go here Fender Bass Diagrams (http://www.fender.com/support/diagrams/#basses)

A good starting point for passive basses.

You're good to go with those values. These guys sell me CTS kits(or individual parts) with a switchcraft jack for a good price:

Before you're set on standard wiring, check out http://www.has-sound.com/, they have a bunch of cool wiring harnesses with extra features.

Thanks Guys, that is great information. I found a set of pots on E-bay for $2 each, and will set it up as I had found on seymore duncan, also that same schematic was on guitarelectronics.com
