YACK YF-2 Fuzz

George Giblet did a trace (and some guesswork on the cap values) on FSB a few years back. The cap values might not be 100% per original, but according to George, those should be at least close enough. There are a few ideas on this late 60's circuit that are not present on every single FF/TB-clone out there, so i thought this migh be nice and fun little circuit to try out. Not sure if i built one back when this was drawn. Seems i can't remenber everything that went on in 2019. Seems so long ago now.

However. This might be fun to build and to tweak to your liking. Note the transistor pinouts as those match 2SC828s. Parallel polarity protection is in place etc. I'm fairly certain you'll get this sounding good with modern values for resistors as well.

    I just redrew this so I could use E-B-C transistors, like 2n3904. Going to give it a shot tomorrow and report back here if it fires up!

      Você poderia me ajudar? Eu não entendo a ligação dos componentes, nos caminhos da trilhas

    hi,
    I've made the alternate pinout version of this layout
    see here: http://guitar-fx-layouts.238.s1.nabble.com/Yack-Fuzz-YF-2-verified-td50654.html

    and it works,
    although I have to turn down the volume pot on the guitar to make it sound nice...
    otherwise the gain / fuzz seems to be maxed all the time, and the pot has very little effect....

    when the guitar volume is turned down to 7, the FUZZ pot becomes much more functional...

    I'm no fuzz expert (yet! :)), I like the dense low fuzz it gives...
    the bright switch makes it too bright to my non-expert taste

    I think, this is a good circuit to experiment with,
    and the already available sound samples are a good source of inspiration

    and interestingly enough, there is an FY-2 fuzz, too, which seems to be identical :)
