FM3 MARK II Turbo Compared to the standard FM3, the differences were faster operation (feels about twice as fast?) and improved audio output quality. It has a wide range of settings, and the operation felt the same as a real vacuum tube amplifier. I've switched to the AXE3, which is a stationary unit, and I don't have any opportunities to play outside, so I no longer need it. It hasn't been taken to a studio, etc., and I bought it new just two months ago, so I think the condition is good. The protective film has been on since it was new. Included: Cable, instruction manual with serial number
