My neck and middle pickups (Ibanez V7 and S1) work good. They have normal amount of gain and are loud. I have changed ibz V8 for Steve Morse bridge and despite it has 450 mV output it gives less gain and it's less loud. I've soldered red wire where was previous red wire, black and white together instead ibz white wire and green with bare together to volume pot. Have I soldered it bad or something? Maybe in wrong place?
