What can I say? I test all amps at relatively high volume with a variety of cabs and the MTL sounded considerably more compressed than any other of my amps at that time. I'm not saying it was ENGL Powerball compressed but still more than I usually like. Its voicing was also more scooped which gave the impression of the amp having more low-end than the UL for example but this also resulted in the UL almost burying the MTL in a band context. I prefer my tone to be tight and somewhat mid-heavy and I like a lot of low-end if it doesn't take away from the overall tone and from that perspective the MTL didn't cut it. My friend (the MTL owner) speculated I just didn't like the MTL's diode clipping circuit but I'm pretty sure that's not it.
But since my friends/old band members will have our annual meetup in a few weeks at my place where we always end up reminiscing about old times and such I already wrote that he should bring the MTL. After that much praise in this thread I'll give it another try.
