Hi all. I have a buzz issue that I think I've narrowed down to my amp, but I wanted to check whether I'm missing anything. Please let me know. Amp: Fender Rumble 15 (10+ years old, from a starter pack) Bass: Fender MIM P Bass (1 year old) When everything is set up and being played, there is a minor buzz that gets worse when I move my hand closer to the pickups and goes away when I touch the strings. Things I have tried: Same amp, same bass, same cable, different location - Still buzzes Same amp, different bass, same cable, same location - Still buzzes Same amp, same bass, different cable, same location - Still buzzes Different amp (Vox amPlug), same bass, same cable, different location - NO buzz All of this seems to add up to an amp issue, which wouldn't surprise me given the age and price/quality of the amp. The only thing that gives me pause is that most of the time when I see this type of issue described by others, the cause it not usually the amp. Also, the only other amp I have on hand to try (thanks to COVID) is a Vox amPlug, which isn't quite the same as trying another real amp. Any thoughts or recommendations for other things to try? Thanks!
