    My amp has started making an intermittent crackling sound usually when I hit the mid registers. Its not the speakers I don't think because it comes and goes. It sounds more like something electronic. It also started before a gig when I used my Tech 21 Sans amp to input an SVT-like tone. I didn't have the SVT level any higher than my usual tones but the distortion sounded really bad and when I switched back the crackling sound stuck around even when I bypassed the DI. Perhaps I damaged the amp input, but I don't see how.

    Here's a video. It takes me a few seconds to find notes that will cause the crackling, but by the end, you can here it pretty strong. If anyone has any suggestions for troubleshooting, I will greatly appreciate it.

    Mine does the same. Usually at lower levels. used only as a home practice amp, never gigged.
     
  3. It sounds a bit like the speaker(s) to me. I had that happen to me in another brand cab and had to replace 1 speaker. It sounded exactly like that. I had my buddy play while I pushed on the front 5he speaker to find the issue. I spread my fingers out and pushed on the rubber surround gently to get it to stop. The top speaker in my 210 was the bad one.

    If that helps any. Try it and see.
