I have a Riot and have used it so far on gigs through a Metro Plexi (100 watt head) a 2x12 oversize cab w/scumbacks, an original '65 Deluxe Reverb, a LSS, backlined some solid state Marshall, some Vox AC30 reissue and direct through a Vox amp sim on a Casino gig. I think it's a great solution for high gain in a pedal and I have yet to plug it into an amp and cringe. It saturates really nicely and gets thick while retaining zing. It doesn't really compare to great amp distortion though imo. It doesn't do "creamy". It's not "my" sound by any stretch but it's fun to play and has a lot of life to it. I would say that it's a bit of a generic tone, albeit a really great version of generic but that's just me. I'm sure others are crafting a strong signature sound with it while I type!
