EQ2 user here aswell, best eq on the market by a long shot. I was able to use pre and post eq and shape the tc50 into a very convincing british crunch, tweed and twin just using the clean channel, being able to choose freq and q is a godsend. Prob the most used pedal on my board and melts well with the TC50... almost have the high gain channel doing deizel heavy aswell just a little more eq tweaking to do.
Just watch that input dbu from the mesa loop send when on the clean channel, if you push the preamp too hard you can exceed the max dbu the eq2 can take, but im talking vol and gain past 2pm. I love how this amp takes to preamp eq'ing, dial the amps sweet spot in, then fine tune the tone and gain level with the preamp eq, then do the same to the power amp section and theres so much you can cover... amazing circuit
