B&M Champion Fuzz Unit
Another vintage British interpretation, pretty much identical to
the Jumbo Tonebender. BC184C may be hard to come by, so try
others. Looking for around 600hFE in Q1 and Q2, 150hFE in Q3.

Stoned Cleric
Stoner heaven, based closely around a Ram’s Head 74#1 but with different
cans and a different emitter resistor in the first gain stage. Awesome stuff.
*BC549C pinout is the opposite to that shown on the PCB, so flip them.
