I recently acquired an American Jazz Bass with a Badass 2 bridge, Moses graphite neck, and Dimarzio Ultra Jazz Pickups. the pups are double coil Jazzes with four wires. I took it to Mike Lull Guitars to have them do the wiring for me. It now has a master volume, master tone, and a pan pot. The volume is a push/pull switching the neck from parallel to series, and the tone does the same thing for the bridge pup. I now have a Jazz that can sound like a two pickup P-Bass! Neck pup soloed and in series it sounds like a P-Bass, and if you pan to the middle I get that great P/J sound. In the middle with both in series and it sounds like a two pup P! I like having it in the middle, with the neck in parallel and the bridge in series - it sounds nice and thick, but with great articulation. Anybody else try this? How did you like it?
