This is a very basic design, but it still puts out a lot of tone. The design is based off the Fuzz Face, but it does have some modifications to it. It implements two germanium transistors that give it such a warm tone. The Germanium Fuzz comes in red with the transistor decal. It does support a 9v DC jack. Single knob for fuzz control while later revision will include volume.
The transistors used in Germanium Fuzz are two MN38A Russian Germanium transistors. They are not the highest quality, but the design is a great one and is very simple. The few I tested have a hfe of 100-120. Most pedals made use the 105hfe transistors.
