I picked it up from a pawnshop as part of a lot of broken gear. It was blowing fuses because all of one specific type of capacitor (little, black, almost looks like a diode) that goes from the power rails to ground had all shorted over time. Anyways the unit has very nice sounding inductors in the EQ.
