Hey UG,

I have a VOX Valvetronix VT100. It's not the newest model, its the second newest and I got it once it came out (1 year ago). I took the amp in the back of my truck to band practice, and it was moving a lot since it wasn't tied down nor secured. The next time I plugged it in, the volume faded in and out and it's been doing that since.

I already tried factory resetting it multiple times. I've tried changing the cable, guitar, power strip, and even outlet.

Does anybody know what could be wrong with it? Is it something I could fix myself without having to take it to a shop?
