At the other forum I saw a cool fuzz from an older article in Radio- Electronics in the Davidoff library.

Look for

Jack Jaques "Solid State Fuzz Box"

I like how it has a simple mixer for the fuzz and clean sound

One can use NPNs and a N-channel flip the power and electro cpas

Did a search and found this look on page 34

There is a transistor curve tracer before and other cool things

It would pass for a Boutique pedal  :icon_mrgreen:.

HEP57  Silicon PNP, HFE typ. 350

According to the water analogy of electricity, transistor leakage is caused by holes.

the fuzz signal is out of phase, it might sound like a Gretch Contro Fuzz.

i have a lot of old silicon transistors from that era, i might have some of those HEP transistors, ill take a look tomorrow.

cheers

EDIT: i don't have those, i do have one other HEP transistor, its the HEP55
friendly reminder: all holes are positive and have negative weight, despite not being there.

cheers

Holy tone-suck, Gusman!!

But looks like an article on antenna rotators (what??) got overlaid.

It was from 1969

I was thinking about how it might sound with a bass with the mixed in clean signal

Yes the fuzz is inverted polarity(if that matters with a fuzzed destroyed signal)

Things could be "fixed"

I did like the 2nd stage had a JFET at the input of the mixer output part

Hello,
thanks for that cool fuzz. I´m glad, to see sometimes some new Designs ;D

Ok, what a concidence,  the Cover page, ie page one, hints at my next project.  Top secret r and d, will be done soon, parts coming tomorrow.
Stay tuned, no antenna rotor needed, lol.

^ we shall see. I hope it isnt going to be a radio. That 1969 magazine has lots of cool stuff in it.
