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.
Review: Five Stars - Great delivery. Product functions as it should.

## 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.

Great delivery. Product functions as it should.

### ⭐⭐⭐⭐⭐ Nintendfuzz ...
*by J***A on 20 June 2012*

This goes from a really awesome sounding fuzz to a nintendo-esque type Octaver-fuzz sound with weird nuances. This is a pedal for an experimenter. While my description of its sounds may sound weird it is musical. I believe it's used in some White Stripe songs. You'll notice it immediately when you hear it. Doom Metal riffers (who will love its insane fuzz) to "electronica" experimenters will be pleased by this little monster. The only downside is volume. It tends to be tamer than many of my other dirt pedals. Constructionwise, it'll survive a nuclear war. This thing will last longer than you will.
