One thing I found out is don't be afraid to turn these amps up. I had them all straight up noon on the master volumes. Sounds so big. It's not that loud. Not like my plexi or Diezel. Just big and punchy. Really feels out the tone and very expressive. At least get the masters above 9 o'clock. The TC sounds the best below that. The TC seems to sound great from the get go on the volume knob. Still better loud though.
