"I never really found an amp that could do more than 1 or 2 things really well. The M4 changed all of that. It basically allows me to have 8 different tones on hand. I can go from a cleanish Plexi sound, a hot-rodded Plexi, a clean black-faced Deluxe to an overdriven Deluxe to a modern hi-gain to a Dumble to an AC30 and the amazing thing, it does all of these sound really well!! I've heard these types of claims from amps in the past but the M4 is the first that actually delivers in spades. Absolute genius!"
