This is a fuzz pedal from Danelectro's FAB series. It's quite versatile, giving the impression that you can switch between fuzz, overdrive, and distortion sounds. It also responds well to the guitar's volume knob, allowing you to create a clean, bell-like sound when rolled back. It's one of my favorite pedals, but I have too many fuzz pedals and it's not getting used, so I'm selling it. Sound tested and confirmed working. No issues. Thank you.
