So I hooked up everything as stated above, black and white wires on each pickup are attached to eachother, soldered then taped over with electric tape. I soldered the green and red pickups wires to two, two-pin connectors so i can slide them on and off of the pre-amp. I have the ground going to the black wire that's coming off of the jack, and I also added a little extension for the current ground. Problems: 1. Huge amounts of hiss when the mid is selected above -3. 2. Huge amounts of hiss when any trebble is there. 3. Heavily distorted, non ear pleasing sounds. 4. When you touch any part of the bass that has metal it makes a clicking noise. Things I've tried: 1. Changing grounds. 2. Checking wires, haven't replaced any just made sure all solder points were there. 3. Different amps. Just tried to play through it using my Mesa M-Pulse 600 and svt cabs. It sounds better, the hiss is much more minimal, and the distortion isn't as bad but it's still not "right." Does anyone know what's the plus and minus for the Dimarzio ultra jazzes? Green = plus?
