Maestro FZ-1B Fuzztone (2 transistor version)

This was (I believe) the 3rd iteration of Maestro's Fuzztone fuzz pedal. The first 2 used germanium transistors and AA batteries. This marked the changed to silicon transistors and a 9v battery. Originals had 2N3860 transistors, but 2N2222s or 2N3904s would probably work just fine. Couldn't find any info on the diode, so socket and experiment. I also couldn't find any demos of the 2 transistor version (there is also a 4 transistor version of the FZ-1B), so you'll just have to make it to find out!

    This one's 1.8" wide and 1.1" tall. The Bosstone is 1.8" wide and 0.85" tall

    This layout is verified :D, sounds good.

    Have you followed the scheme of Andrew Carrel for this design? Do you know if the original scheme works or is there an error?

    I see difference value of the electrolytic cap

      I drew this up 4 years ago, but if memory servers I think it was Andrew's schematic I used. I don't know if the original schematic is accurate. I know there are some old Maestro schems that are inaccurate. The layout is verified though.

    I would like to know if anyone who has built this circuit, what transistor did you use. I'm unable to source the 2N3860.

    Ha, I must have missed the part about using 2N2222 or 2N3904, WHICH I have in my bin. I tried a 5817 diode and 2n2222'S. Sounds real nice. I verify also. Thank you.

    The FZ-1b is a 4 transistor circuit that uses a dual gang pot for the output balance. This circuit is very different to the FZ-1b, although the FZ-1b uses silicon devices. I just repaired an original FZ-1b that I'm going to clone. I found this page looking for info on others attempts.

      La primer version utilizo solo 2 transistores.

    Hola! hay un error en el valor del capacitor de 15 nF, en el esquema original es .22 / 220 nF o .15 / 150 nF.
