i played on one of these things last night, through a mesa 2x12 cab with vintage 30's in it... was able to dial in the exact tone i dial in on my vamp on it, and i felt so at home playing through it. using my Rhoads V of course, with dimarzio x2n in the bridge spot, and duncan seth lover in the neck spot... it even sounded great when i was playing with my neck pickup... just all around great sounding amp, i was very impressed by it... it really friggin screamed, probably the coolest sounding tube amp i've ever played through...

and 60w is definately plenty for live... maybe i'll try and get one in the future

the thing just screamed, yet it was so chunky, i had the gain knob at maybe 3, when i first played through it the guy who owned it had the knob at 5 or so, holy hell that was a lot of gain, but 3 is still pretty gainy... and it is a master volume type amp, so it sounds great at low volumes too... i'd love to try it out live...
