Hi guys!
I'd like to make some experimentations with my own design of fuzz.
I've got a question. I'd like to try using Jfets like the J201 and adapt it to circuit close to the fuzz face or maybe a tonebender. Since the pinout is completely different, do somebody know how to use them before I tweak the circuit on the breadboard?
Thanks
JFETs are significantly different than BJTs in their biasing requirements. You could definitely build something with a lot of the same topology, but you'll need to change the bias network a lot. It's my guess that it probably won't sound that much like a typical fuzz face circuit (not necessarily a bad thing).
I thought it would sound different and interesting. I just don't know what is the equivalent for the emitter base and collector on these...
In much the same way that transistors were used similarly to some tube setups, so were JFETs:

Runoffgrove has some other useful articles like this ... You can also try Jack Orman's site for some ideas.
I'm thinking your future involves an awful lot of bias pots on your breadboard ;)
