I have been lucky enough to come across a stash of vintage Germanium transistors (Texas Instruments and Mullards).
The first pedal I have built with some of these is a fuzz face with mojo components in a massive enclosure.
I can honestly say that this pedal sound fantastic; its my favourite fuzz face I have ever built.
The pedal is a PNP configuration using a TI 2G371 and 2G345A. It also has mallory caps for the mojo factor.
The only mods were using a 100K vol pot for a brighter tone and replacing the 470 Ohm output resistor for 1K for a higher output level.
Do big enclosures, axial components etc. add to the mojo? Who knows but it certainly looks cool!
Next in line is a Tonebender MKII in a similarly ridiculously oversized enclosure 😉
