Ok, so by the looks of it, the GB Shuttle 6.0 has probably the most wattage for the dollar out there at the moment. I live in Japan, so the light weight of the 6.0 combined with the cheap US price (it costs $1600 here) makes buying one from the States a very attractive option. The US price even beats out second hand amps even with comparable power. What I am wondering though is, most of the owners of the 6.0 on TB seem to be using it in Jazz or rock or blues contexts. Is anyone using it in a more "metallic" context? Specifically, can the GB 6.0 handle slower, heavy doom? I play in a power trio with a half stack guitarist and drummer. My sound is low and mostly mids, fairly wooly but not too distorted. The idea would be to pair the head with either a 2x15 or a 4x10. I recently found a SWR Goliath III 410 at a great price and at 900W @ 4ohm it looks like the cab for me... Anyone out there have any advice? Can the GB 6.0 handle doom?
