Looks virtually unused until you turn it over and see some Velcro glue residue on the bottom.

Perfect working order.

Stunningly versatile.

Channel A has the traditional volume tone gain controls but adds a bass/mids boost switch.

Channel B has three band EQ and a comp button which switches between soft clipping (overdrive) and hard clipping (distortion).

In addition you can decide the order of A and B!
