I don't know about this particular pedal, but a while back I tried a Boss OD-20 "Drive Zone" multi-distortion modeler similar in concept to this one. Really didn't care for it. It had 22 different fuzz, distortion and overdrive models, and I found about 4 of them that sounded reasonably good, but none that I liked as well as my various analog stompers. Most of them struck me as very unnatural sounding--definitely a "processed" feel, for lack of a better description. Several were just plain ghastly sounding--harsh and grating, with WAY too much nasty top-end. Got it off eBay and it was back there again within a week....
