Monolith Oracle Fuzz
This is a pretty cool fuzz box. It's a cross (sonically anyway) between an early Vox Tone Bender and a Big Muff. It uses PNP germanium transistors, but still uses a negative ground power supply. Originals have OC76 transistors with hfe of around 100 for Q1 and 300 for Q2. 300 is high for most PNP germ. devices and might be hard to source, but I've read of people using trannies with typical Fuzz Face gains (70, 100) with good results. The switch on the original is a push/pull on the 250k pot, but a DPDT switch can also be used.
