I have a couple of fuzz boxes from the man himself Dennis Cornell. Dennis built the original Fuzz Face's and can boast Mr. Hendrix on his list of clients. He knows fuzz! There have been a couple of boxes from Cornell, the first one being the Fuzz Face and the second being (randomly) the 1st Fuzz. Both are FF circuits and bosth are NKT275's. Head to head do they sound different? You tell me..
