Grounding Issue... I think.

    My new-to-me '73 Guild JS-2 has just developed some kind of annoying popping sound when I touch the pickup switch, the bass-cut mini-toggle or the chrome pickup cover... It doesn't happen every single time, but it happens enough to annoy me.

    Keep in mind I have very little electronics knowledge, but it sounds like a grounding issue, right? So what should I look for to determine if that is what the problem is, and how do I fix it? I've proven that I'm pretty terrible with a soldering iron, so is this something I should have my tech take care of? Thanks guys!

    If your bad with a soldering iron, your best bet is to take it to a tech. But it sounds like there is a loose common/ground somewhere. Does it happen when you are touching the strings or when you are not touching the strings?

    I'll have to try it again when I get home. I think it was happening when I wasn't touching the strings mainly. Hard to say though; this thing neck-dives like a beast so I may have been holding the neck with my left hand (therefore touching the strings) to keep the neck from plunging.

    The annoying thing is that I just got a setup and asked the tech to look over the electronics. He told me it looked reasonably clean considering it's age, and that he could clean it up i wanted, but that it didn't really need it. One week later it starts a'poppin. It wouldn't be a big deal, but I can only get out to him on weekends, and I have a gig friday. Bleh.
     
  4. Replace the switch.

    Actually just last night I finally cracked open the controls and noticed that some of the foil shielding had peeled away from the inside of the cavity... i stuck it back in place, looked confusedly at all the wiring and just made it a point to make sure no exposed joints or wires were touching that shouldn't be (they pretty much looked fine though) and closed her back up.

    Took it to practice a few hours later and she worked like a charm. I'm assuming it was just the foil getting in the way, but being the electronics noob that i am, who knows. Maybe i wiggled the right wire.
