I’ve not tried the MM range but did have the LM3 and LMT (tube). Great amps, worked nicely for a traditional Precision sound but I couldn’t get what I needed for my punk band which was that gnarly/gainy sound from boosted hi mids and treble. Seems like the eq points of the MMs have addressed that - not specifically for me I might add, but I’m sure that’s just because I didn’t ask…..
