Hey guys, i have a really annoying problem with my AMP. It worked pretty well til the last days but now it starts having some problems. If i play any note and hold it, it doesn´t ring out as it should but it fades away as if i would use my volume knob extremely fast. I already did a factory preset on my AMP but it does not affect this weird sound. I am pretty sure that is is the Amp because i tried out two cables and two different guitars. Would be nice if you could help me :) thanks a lot
