The biggest component of Timmy\'s tone, aside from his hands, is his guitar amp. A Mesa Boogie Nomad 1x12 that he pumps thru a 4x12 recto cab. The foot switch to control the amp is dead center in his pedal board and is the majority of his distortion, beefed up with the aforementioned pedals. I am also a mesa user and have had a few discussions with Tim about how wonderful there amps are and how he should think about utilizing the effects loop with such a long chain. He has has taken care of the signal loss instead with a buffered line level pre- in his pedalboard. He did use to rock a Mark IV which is similar in sound to the his current Nomad rig.
