This originally started as a Catalinbread Hyperpak fuzz clone from Fuzz Dog, but I didn't really care for the tone. I may have messed something up too, as I had a bad pot. Since I have been building fuzzes in these 'matchbox' enclosures, I haven't made a Fuzz Face, so why not? I had good results with a General Guitar Gadgets Tone Bender, so I tried their Fuzz Face, and gain staged some old stock 2N4124 transistors. Sounds great!
