Another TF user who only tweaks the 'Timbre' and 'Enhance' dials (though I once used the semi-parametric EQ to roll off everything below 40hz on a bad boomy stage). I've done A/B comparisons with a whole heap of amps (Tecamp, Tech Soundsystems, TE, PJ, Aguilar, GK, Mesa, TC, Warwick, MB... to name a few) and I'm still with the TF as it just delivers the goods every time!
