I bought this in the 90s out of the sued bin at bob's rt13 music... its was like 25 bucks. I figured it was way cheaper the a dynacomp and had more controls so how could it be bad? Well its a noisy little beggar that doesn't have as much squash as most guitr comrpessors, that's how. Typical DOD crap switch. Not sure if mine even works now.
