Howdy gang, I get a loud popping sound when I pull out the push/pull mid control on my Aggie OBP-3. After the initial pop I can click the pot up and down without issue, but then if I leave it alone for a while and then go to switch it again...pop! It's like a static charge is building up. Naturally I attribute this to incompetent wiring on my part and my first thought is that it's somehow a grounding issue, which is usually where I make mistakes. Can anyone suggest a fix or let me know if I'm on the right track re: grounding issue? Thanks!
