I've been looking for a gig-friendly amp, and I'm interested in those two amps: THD Flexi and Budda Superdrive 18. Based on reviews, technical data and the soundclips I have heard, I think they will suit my needs. I want a amp with a "cleanish" (not quite clean) and a fatter lead mode(moderate gain). My musical preferences are SRV, Stones, Zeppelin.. How is the Flexi (in 20 w mode) compared to the Superdrive? I'm thinking of the sound (bright/dark, texture, clear/muddy etc) and "feel"/response.
