Does the Tonemaster twin need to be as loud as its tube counterpart. Thats the #2 complaint with using a TR. Thats its just too loud for anything but an arena. So I imagine the TMTR is loud enough for any application except maybe an arena.
Guess that's up to the user. It might suit you or it might not. I've found that a Twin's strength is it's ability to cut over a very loud and aggressive drummer and larger bands with keys and horn sections without breaking up into total overdrive. In this regard I find it just barely adequate, so have others, which is why the quad reverb came into existence.
