Finally played a Model T. sounded way different than I thought. really crazy how much gain it has for an early 70's amp. alot brighter than I assumed, considering the bands that use them (Sunn 0)))) and a bunch of sludge metal bands). it was surprisingly easy to get a really raw, ripping rock tone. and HELL THAT THING IS LOUD. sounded best IMO with the input volume around halfway and the master up as loud as I could get it without disintegrating walls. really shines with less pre-amp gain and more poweramp gain, but it actually sounds pretty good at low-ish settings dependent on pre gain. definitely going to have to pick one up when I can. damn all those bands for making them so popular and therefore expensive.
