I thought I was almost finished with my warmoth project, but it turns out that I have something wrong with the wiring. I'm using the following wiring diagram http://www.seymourduncan.com/website/support/schematics/p-j_bass.html However, I'm using sadowsky p/j pickups and a dual 500k concentric pot for the volumes. This is my first electronics project (basically), so I'm not wise on how to trouble shoot with a multimeter (although I do have one). I did a pretty messy job, but it doesn't look like anything is cross connected, and it is wired as show in the diagram. I've been soldering all of the ground connections to the back of the concentric pot. Anybody have any ideas of what to check or what would cause this? The volume does turn down correctly, it just never goes completely off. The bass is not strung yet, I'm testing by tapping on the pole pieces with a hex key. You help is much appreciated! thanks.
