Listed is a MXR Custom Shop Custom Comp Guitar Compressor Pedal. The pedal is in great shape. I originally bought it from a friend because I had two pedal boards and my Dyna comp went out on one of them. I never really clicked with the pedal. I can hear it is doing what a compressor should do, but since I really only use compressors as line drivers I think it may have been too much for me. Not interested in trades .
