I've read a number of good reports on a RAT run into a Vox amp. So I'm thinking of getting one for my AC15. I've seen the RAT2, the Turbo Rat, and the You Dirty Rat. Any thoughts on the differences? I'd be using it mostly for classic rock solos, maybe fuzzed out wah psychedelic freakouts. I've found you can get very demented with the Crybaby Classic and lots of gain.
