I have a TM 18, 36, and a Grandmeister. I run them through a Mesa Recto 2x12, 4x12, and a Red Bear 4x12. Thin and fizzy would never be terms I would use to describe them at stage volumes. The first time I played one I was impressed by how massive they sound. If you don't like EL84s they may not be your thing, but you should try one out. The 36 watters sound better than the 18. The third tube does make a difference.
With the variety of tones, full midi capability, built in effects and the power soak you'd be hard pressed to find anything like it in it's price range honestly.
I've been gigging with the Meister series (only running 18 watts) now for over a year now. I have a Red Bear, Triple Rec, 6505+, Peavey Ultra, Blackstar HT100, 2 H&K Switchblades and a Triamp MKII sitting on the bench. It's so much easier to get a great, full tone at club volumes.
