chadgrooms Posted August 23, 2015 Share Posted August 23, 2015 Hi all. Weird issue here -- I have a newer HD500X and when I plug it into my Mesa Single Rec half stack, I get a crazy loud pulsing buzz. Works great when I run the same line out to my audio interface This buzz happens whether the line 6 has power or not, and with all cables or just the line out plugged into the amp input (both L & R). I tried multiple cable brands/lengths, all the way down to 5'. I tried different pedals and had no issues. I tried flipping the physical switches on the HD. I tried multiple outlets in the house on different breakers. The house is newer and we've never had electricity flow issues. Unfortunately I don't have any other amps to try, but I can always run down to the local Music Go Round if it comes down to it. I've been running live multi-effects setups with amps for years and never experienced anything like this. Video clip below. Anyone have any suggestions? https://www.youtube.com/watch?v=7R3fIg1iJDc Quote Link to comment Share on other sites More sharing options...
