The pickups in my Squier Deluxe Active Jazz V have 3 wires. White, Red and Bare (no insulation). They were wired for passive use from the factory. The White was hot to/from volume pot. The red and Bare were twisted together and grounded. I re-wired wired the bass for passive-only and a series/parallel switch. No battery. Started poking around the Duncan site and came across these active pickups: http://www.seymourduncan.com/products/basslines/cutting-edge-1/ajb5_active_for/ and then looked at the wiring diagram to see the suggested wiring. http://www.seymourduncan.com/images/products/basslines/501035-100.pdf I see these active pickups have Red, White and bare wires. The white is to the volume pot, the bare goes to ground and the red goes to Battery. What are the chances that I can use the squier pickups as active pickups being that they have the 3 wires??? Seems that you don't really need a preamp to use active pickups either, which I didn't know. I guess the preamp is optional. I have an empty battery compartment in the bass, and I was wondering if I can fill it with a battery and still have my V-V-T-T setup.
