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
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
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.

another mosfet of jfet MIAB?
cheers, Iain
^ we shall see. I hope it isnt going to be a radio. That 1969 magazine has lots of cool stuff in it.
