JEN: FZ III Fuzz

Also known as the JHS & Ricken's Fuzz - the JEN FZ III Fuzz is a simple silicon variation on a Tone Bender MKII.  

First things first - this is reported to be very bright, so maybe increase the 10n capacitors to something a little larger to let more lows through, or add a 10n to ground before Q1 to cut the highs (like a Tone Bender).  However, if you increase the caps too much, it could all turn to mush.  Increasing the 1.2nf cap has also been suggested.  Yet to breadboard this one, so I don't have a firm opinion either way.

I haven't been able to spot the value, but I have seen some examples where the diodes look like Schottky diodes (blue and black).

  1. Great site, thanks. Sorry to be pedantic, but it's not quite a tone bender as the first stage is a buffer not a boost, plus it uses diodes for clipping.

    1. Yep - that's why I said it's a variation on a MKII. Which in my mind means similar, but not the same. I could have also described it as a fuzz face with a buffer up front and clipping diodes.

      Anyways, now the two or three other people who will read the comments can decide for themselves. ;-)
