Yeah I'm very interested in that new head actually. I think Hartke is generally underrated for their amps. Whenever I play through one I'm like, "Why don't I have one of these?" And after playing my little booger here, and turning up some tone controls and volume, I'm impressed more than usual. Maybe it's the different speaker, which is also drawing a little more power from the 120 watt head, since it's 4 ohms and not the old 6 ohm model.
Anyway I think what I like about it is the lack of what I'll call 'hype'. Not a real complex sound, but it's got some shaping attributes in the controls. Dunno, it sounds real solid to me, just liking it.
