I recently bought the Orange Rocker 30 which I am in love with. It's built in "dirty" channel gives me the nicest distortion tones I could want from an amp. There are times when I'm wanting a bit more, something a bit more heavy and insane. I used to use a Fuzz Factory with my old amp, but with the new amp I can't seem to get the same great tones I used to. I think that I'm going to need to sell it to buy a new fuzz / distortion pedal (I already have a tube screamer for boost, I just want to expand my tonal options), but I don't know what to look at to compliment the already great distortion sound. Any suggestions?
