This is a Visual Sound Comp66 V2 that I bought used. I bought it to replace my Route 66 pedal. I got it and needed to velcro it to my pedalboard. Had to remove the battery cover. You can see that it is damaged. I only use AC power so no issue for me. This pedal is a great compressor. It compresses and sustains but does not squash the tone. As a player who plays mainly cleanish Country and uses Telecasters exclusively, my compressor is always on. This one sounds fantastic! $50 + S/H in CONUS.
