The tonal ranges of this amp are incredible - I have been playing it all morning in spite of returning home very late Thursday only to find I have no air conditioning in 85 degree weather. This amp is truly superb and has exceeded all my expectations.
Here is some technical feedback - I am currently running it in the 16 ohm position through an open back cabinet w/two Fane Axiom AXA-12 100 watt speakers. The crunch, low end growl and bite you can get out of this combination is fabulous, plus, I cannot believe the clarity and articulation. I think I am going to take the plunge and put four of the same 100 watt Fanes in the cabinet I purchased from you - it will weigh a ton but I am now certain it will sound incredible.
