It is a great amp but it's still price bound. Get an fx pedal and you'll sound a lot better. There is not knob for mid. You have to manipulate the other two to make the instrument sound like that. The knobs range from -10 to +10 which is not only interesting but beneficial, especially the Treble knob. The distortion channel is pretty good but nothing crazy. Pair this with an fx pedal to get full benefits.
