I work as a session guitarist, mostly pop stuff but these days that means you need a pretty heavy guitar sound. Obviously I need a good clean also. All three are a similar price. The Shiva seems to have the least gain of the three. I'm a bit confused though as the videos i've seen of Rafael Moreira and Justin Derrico seem to be pretty high gain?! I want a nice fluid solo tone. I know the XTC and 5150 can provide this but maybe I'm getting a bit greedy with the gain. I dont know! Help!
