Probably the best fuzz pedal I've ever heard. I've owned several other fuzz pedals over the years and I was never really satisfied. The fuzz head now has a permanent spot in my setup.

This is another Keeley best of the best. You can tell Robert is an engineer by the quality of his pedals. This is the best Fuzz I have heard. Suhr Tele > Fulldrive II > Keeley Fuzzhead > Keeley Compressor > Analogman Chorus > Keeley Boost > Carr Rambler. A fuzz that is actually musical. Has to be heard, cant put into words."

The Fuzz Head is another high quality pedal which delivers big time. Robert is able to breathe new life into your tone through his pedal mods and custom designs. As my playing and equipment has improved over the past couple of years, the quality of some of the cheaper pedals comes into play. I have had Robert modify my DS-1 (Seeing Eye Mod), BD-2 (Phat Mod)and CE 2 (Speedy Mod) and MT-2 (Twilight Zone Mod) with fantastic reults. I also own his Compressor and Java Boost pedal with very good results.

I purchased this pedal as soon as it became available as not only is Robert a great engineer he is able to develop pedals which are very musical and enhance your tone and playing enjoyment. I have no hestitation in recommending Robert's pedals.
