For me the TE sound I want is clear, full and punchy. I found the extra facilities on the SMX (tube pre and compression) didn't add anything for me and maybe even took something away. From a simple ergonomics perspective I prefer the longer travel of the Series 6 graphic EQ sliders. I went for the 200 watter because it doesn't have a fan (excellent for studio/low volume practice) and is feather-light compared to the larger UV lit, fan cooled models. Oh, and it's the loudest 200 watt head I've come across to date. With the pre gain set at about half way I barely need the output above 2! I doubt the output control gives a linear increase in volume but I'm not brave/stupid enough to see where its limit is.
