Well I saw Pete Thorn's video, and wanted to check it out. I've been thinking about an AC pedal for a while, and with a GC coupon, the price was right. Long story short, I'm really really impressed with this thing!!! IMHO, Boss hit it out of the park with this little guy. It's super versatile. Pure AC flavored clean all the way through extreme gain on the Sound knob. EQ knobs are effective at shaping the tone based on where the Sound knob is set. LOTs of volume if you want it. I haven't bought a new boss pedal in years. Tried it out through a fender deville and a strat at GC, and it was awesome. Got it home and it plays beautifully with my Classic 30. My Blackstar is slightly more picky, but it still sounds awesome. Super Champ XD - awesome. Easy to tweak, too - very intuitive. It seems to stack well with my RAT and my TS9 (of all things?). My favorite settings are in the middle of the Sound knob, which is cleanish-grit to crunch. Pics will be up later. Awesome pedal. Well done, Boss.
