Operation has been confirmed. I am selling this item to organize my equipment. I used it for recording vocals and guitars. It's a very easy-to-use compressor. I used it with care, so there are no noticeable scratches, but please understand that there may be some scratches from normal use. The main unit, adapter, and box are included. I will wrap the box in bubble wrap before shipping, but please let me know if you have any special requests. The Golden Age Project "COMP-3A Jr" is a compressor/leveling amplifier that replicates the legendary vintage "LA-3A."
