Have been meaning to sell this for a long time, but closed my PayPal account years ago after a security concern and never opened another one. The Option-FET is in good shape with a few paint scratches on the back (shown). Barely used, as it is way more compressor than I need for what I'm trying to do. Hoping to trade straight up for the much simpler Keeley. It didn't come with a box when I bought it, but comes with power supply (shown). Only interested in a trade for a Keeley. Thanks for looking!
