This is probably the most inspiring thing I've played. I am using the Syn-2 and it also helps that I'm using a Fryette 2/50/2
The gain structure is amazing, unlike anything I've tried - it's musical distortion that somehow stays "clean", sparkly, very dynamic and with huge headroom.
The best thing about this amp is it will reflect the attitude you play with. So there is nothing to hide behind, but if you lean into it, it will bring out your real expression. What I think, even playing an open chord with my settings dialled in, and letting it ring out - "that's definitely "my" sound.
I only take one star off because for my taste I would prefer a bit more clean headroom in the green channel, and a bit more travel in the gain knobs before it starts to break up. But that's a matter of taste and might also be something I adjust to and learn to get the most out of (I've heard that this has HiWatt "DNA" and that's one amp I am not familiar with at all).
