They sound really nice Andy. They have that true valve sound but to get a heavier distorted sound you need a pedal. Even if you swap the lead over to either Top Boost channels. I bought a Soul Food pedal for it, that gets it cranking. I paid a bit over $1,300 for the amp. Guitar World Nerang had them on special. They are 1439 now. A lot of amp for the money with the dual Celestions.
There's a couple of vids of the boys playing here on their FB page. https://www.facebook.com/theoffbeatsofficialpage/ my young bloke plays drums.
