Review: Fuzzy and messy and brilliant - thick fuzz sounds, great when combined with other effects. The one thing this pedal has stacks of, is character, it sounds warm and it crackles and spits when trying to track notes. It tracks very well when playing about the 11th fret though. Reacts differently to different pickups. Unique and fun to play with IF you like noise. Not one for pure tone hunters.

## Questions & Answers

**Q: would this work for a 'sensitive' instrument like a 'piezo pickup' lap harp?...thanks**
A: It'll work, but it's simply on or off type sound. It doesn't respond to playing quietly very well, it sounds like it has a noise gate that kicks in when you pick harder. If you want full on octave fuzz then it will do the trick. But not for dynamic playing such as a fuzz face.
