ARIA DINOSAUR OVER DRIVE DOD-1 Body only. Operation confirmed, no problems. I was using it until recently. The fixing tab for the battery compartment lid is broken (see photo 9). - Power adapter and 9V battery power supply OK - Each knob operates OK - Effect switch operates OK - Each jack OK - LED lights up OK There may be some crackling in the knobs and jacks due to aging. There are some scratches and scuffs on the enclosure due to use. It will only be lightly cleaned before shipping. Instant purchase OK. Thank you.
