I got a C-pig in my 7 string (BC Rich Jr. V 7). At first it sounds like there's way too much bass but after a tweak or two it sounds a lot better. There's a lot of output and it just thunders away and I find the clarity to be good. I had to really change my sound settings a lot. At the moment I only have MT-2, GE-7 or an ME-50 into a 30 watt Marshall to play with. I can make it sound great but amp gets overwhelmed fast so have a Vypyr tube 60 coming next week.
So far I'm happy but I'll have a better idea when I get my new amp. There's a lot of bottom end and the cleans could be better but so far that small amp metal sound of the early 1990's, even though I don't have a HM-2, it's great.
