Well here's something that's new to me, and I feel dumb even asking it... A few months ago we had a week with really dry air. I don't know a humidity percentage to tell you, but we had the kind of nights where you get in bed and see the sheets spark when you move. One of those nights I was playing guitar in the garage. A strat copy I rewired recently was cutting in and out. I could get it to make popping noises when I adjusted the switch. One switch position just wouldn't work at all. I thought it was weird and made a note to inspect it later. Yesterday I grabbed the guitar and started playing. Sounds great. Switch and all pots work fine. No pops, clicks, or static when adjusting them. Same setup, same room, same cables. So, can really dry air mess with electronics? If so, how? If it's coincidence, I'm at a loss for how everything just came back and works fine now.
