Hi guys, I had a pair of Model Js installed, and added an Audere preamp to that setup. Now, I have a fair bit of buzz! It looks like the dimarzio pickups are wired with the black and white soldered together, and then the red into the audere hot and the green into the common. Both pickups have this, yet there is a hum. Shouldn't the white+black be the part that cancels the hum? The part that confuses me is the black wires coming from the pickups. The bridge and neck pickups are soldered to a screw in the cavity, then a black wire from the cavity+the bridge black wire are soldered together to the audere ground wire. Is THIS the part that's wrong? The hum goes away when I touch the strings, bridge, volume knobs, or the plate itself. The audere page mentioned that shielding everything would work. Should I take that step, or should that be something that the model Js do by themselves?
