From the vendor
Clone board of the Kurosawa "The Fuzz". Imagine a Superfuzz, but with better octave, and better chord clarity. While the original is a rare bird indeed, we decided that the second tone setting was way too muffled and dark. We have suggested some minor component substitutes to help improve this. Either way, it's a fantastic hen's tooth fuzz revival. Let the fuzz reign!!
