Clean used Micro 50 II head. Solid, robust build quality. Single channel, with two sets of interactive controls. With any single button footswitch (not included) you can add and mix the upper, 'more gain' row of EQ to the lower, 'clean' row of controls. They are interactive when the upper row is on. A footswitch (not included) turns the upper row on, so it can be used like a 2 channel amp.
I find it warmer and darker overall than my Quilter 101 Reverb head. Quiet at idle, studio quality reverb, usable distortion, apartment and recording friendly. The reverb in these DV Mark amps is nice. This one has a chorus character to it higher up the dial. The heat sink fans have never come on.
