I've got a TH350 which I bought following reading a lot of good things about the amp. I've also got a Genz Benz, Ashdown and a lot of old Trace heads. Truthfully the cabs make a bigger sound difference compared to switching between any of the heads, albeit the convenience of how tiny and light the TH350 is means I always have it with me. The gain control is quite nice to dial in a bit of dirt which is something some of my other amps do not have.
