Is there a germanium FUZZ that uses boatloads of Germanium transistors

Heh, I have so many germanium transistors and I wanted to embark on a project that uses as many of them as possible to diminish my stash lol. Are there fuzzes that use 6-10 in one circuit? I've seen silicon fuzzes go that high.  :)

Don't use them. Store them until their value goes up and then cash them in. :) ;)

You could use them like germanium diodes in a big muff. To match the silicon forward voltages, you would need 8 total. This would be a great way to use the leakiest ones.

I probably have a few hundred.  A rather incoherent local electronics store, that went out of business a decade back, was selling bubble-pak cards with 5 or 6 to a card for a dollar, so I bought fistfuls of them.  Most are leaky or have unrealistically high hfe.  But I use a couple now and then.  Made General Guitar Gadgets' "Boutique Bender" with a trio of 2SB33 transistors, and use a pair as diodes for a buddy's Colorsound Overdriver (Throbak version).  Sounds nice.

I've just bought a few hundred of the 2sb714, high gain but high leakage. I solder one on the back of the fuzz pcb to counteract the leakage of Q1, no need to do that for Q2, but i am up to 3 on a board.

A while back, SamHay posted a Discrete Germanium Opamp build, along with a Tube Screamer-style drive using it. You can find a perf layout for it here. It uses Ge transistors for Q1-3, but you can socket the others and try out more Ge transistors.

build a germanium big muff [there is a thread somewhere] and use transistors for all the diodes.

Skip to Q's socket in circuit for sound,
And variable bias.
Consider each gain circuit as source for noise.
Or..first...
Ge leakage/gain measuring circuit, separated the "good as a diode" leakers, bias resistant devices.

An active EQ and buffer at the end would put a few more transistors to work.   :icon_idea:
