Hey guys, I'm new here and I'm wondering if anyone could help me with my problem. I've recently purchased a seymour duncan triple shot mounting ring to install on my esp guitar for use with my duncan jb (bridge pickup). When I went to install the ring I noticed that there is no bare wire coming from the pickup. There is a green, black, red and white wire but no bare (ground) wire. I'm kind of new to wiring up guitar pickups so i'm wondering if it makes any difference whether the bare wire is there or not, or do I perhaps have to solder a wire to the pickup cover to ground it. Note, there was some hum coming from the pickup before I took it out to install the triple shot. So my question is more on how to ground the pickup if there is no bare wire. Sorry if my explanation of the problem is not clear, if you have any questions let me know. And Thank you so much for looking at this and potentially helping me solve my problem.
