Ive always thought it would be fun to build a tiny fuzz circuit using surface mount (SMT) parts. Heres my creation: The circuit is based on Jack Ormans NPN Fuzz Face schematic. I used MMBT3904 transistors. The circuit was built on a piece of copper clad PCB material. I used an Exacto knife to create small islands of copper on which the components are soldered. How does it sound? I'm not good at describing tone, but this fuzz is definitely usable. Plenty of spit and snarl is available, and cleans up nicely by rolling back the guitar's volume control. In other words, it does what a fuzz face is supposed to do. I'm not sure yet if I will put this in a stompbox enclosure - I already have an great sounding FF on my board: a Throbak Fuzz Haze.
