ampeq, since it seems that I came across to you in this thread as not liking this amp so much, let me say that putting aside some minor issues so far, this amp is a winner. It has the old school sounds of ac/dc, zeppelin, zz top, thin lizzy, and so forth. Mellower sweet blues to more brash and aggressive 70's punk rock tones. Tighter crunch to looser sing. Exactly what I was looking for. Now I'm gushing. For my playing and taste, it smokes my DSL50 for anything but metal, which is off my radar these days.
