I have a bartolini triple coil MME musicman replacement pickup that I was using in another bass. I decided to experiment this weekend and put it in my stingray. I like the sound with the stock preamp. I wired it in parallel according to the bartolini instructions that I had. However, I'm getting a buzz when I touch the pickup without touching anything else. It's loudest when the treble is fully boosted. It goes away when I touch the strings, bridge, etc. The bass is fully shielded...pickup, pickguard and control cavity. Usually, basses with poor shielding buzz when you're not touching anything. And then it goes away when you touch strings, bridge, etc. This only buzzes when you touch the pickup. It's weird. According to the instructions, when wiring in parallel, the hum cancelling coil is not involved in the wiring. I believe it's only used when wiring in single coil mode. Any suggestions on how to fix this? Thanks!!!
