Sound — 10
I use this pedal with a Boss SD-1 Overdrive, my weak Crate 15W amp, a Tradition G12 (Fat Strat copy), and an Epiphone Special II. With the Overdrive before it I can get a really awesome White Stripes tone. It's also good for boosting a signal or lessening it. I imagine it would be great for clean sounds as well. Takes a little getting used to having chords be the same volume as single notes, but it's a really interesting effect.
Overall Impression — 10
Overall, I really enjoy this pedal. It brings some cool tones and effects to the table and really lets me get close to being Jack White. I'd reccomend it to anyone who plays a lot of garage/indie rock, and of course anyone who loves the White Stripes.
