Hi all, I just recently bought a 1994 Ibanez SR506 off of ebay and when I got it, some of the electronics don't work as they should and I can tell that some items have been replaced/doctored. Instead of trying to problem solve 20 year old electronics, I bought a new preamp and am having trouble installing it. Each pickup has 3 wires that come off of it and the instructions don't offer any help when I have such a situation. There is a red wire, a white wire, and a third wire that has a cloth covering. I am assuming that they are +, -, and ground in that order. The instructions that I have (Tone Monster SEB3 v.2 Active preamp) Only give me info for the + and the GND on the blend control. Am I supposed to hook up the GND's or the -'s to the GND on the blend control? And what am I supposed to do with the other wires? Thanks for any help.
