I've become a fan of the genius pedal designer, Bjorn Juhl, and was excited to see this in my digging around tonight. Bjorn is really known for the tube-like responsiveness of his designs and I've come to appreciate his overall sense of tone. I just jive with the frequencies he favors in many of his builds; they feel very musical to me. A lot of folks here enjoy their solid-state amps (especially for backup) and this looks like a solid contender for a reliable alternative. For a moment I got pretty excited and thought that maybe I was about to be convinced to buy an amp with no tubes. I like Bjorn's tones and I think it looks fantastic! The demo sounds really nice but not quite tube amp nice to me. There is just something about the transient response that seems too quick and it's got that stiff emphasis in the high end that I always hear...the same thing that bothered me in my old Music Man amps. It did seem to me to sound really good when he switched to humbuckers though (@2:30 in). Warmed up the tone and you can really hear that it's a dynamic amp. It might be just the thing for someone out there in Gretsch-Talk land? I certainly wouldn't refuse one, sounds pretty killer. $599 List.
