I'm trying to wire up the pickup on a bass I'm making, but I've hit a bit of a snag. The p bass pickup only has one wire coming out of it, and it's clearly supposed to just have the one. Inside the one sleeve is (what looks like) two wires (though it may be three), and I'm completely stuck as to what to do with it. I'm wiring it to 1 volume and 1 tone, then to a jack.
How do I wire it?
PS excuse the crappy camera quality, using my phone camera.
