I bought this preamp for my bass and got as far as installing it before I realized that I'm just going to leave it passive. The preamp is two days old. This is the module and 9v leads only - it didn't come prewired or with pots, so you'll need to get some 50k linear pots for this as well. You can get them from Bestbassgear.com. I added short lengths of wire to each lead so I wouldn't be soldering the wire itself to the pots, that way if I wanted to remove it and sell it I wouldn't be shortening the wires as much.
These sell for $87ish - it's yours for $65 shipped, CONUS.
