ZVEX: Mastoron

Another tweaked Fuzz Face from Zvex - not to downplay the good work of Mr Vex and his amazing array of guitar effects pedals, but it is what it is.  

The Fuzzolo, Mastoron and Wooly Mammoth all have a similar Zvex Fuzz Face variant as a base - thread on DIY Stompboxes, and you can also find the schematic there.

If five knobs and a switch is too much for you, it's pretty easy to remove the switch or knob here and there with this layout.  There are a lot of options...   it is a Fuzz Face after all.

Examples:  

  • Completely remove the relax pot, input straight to the 220n capacitor
  • Sub switch can be removed, and replace the 33n capacitor with a size that you prefer (or just leave it).  The 68n capacitor can then be removed, along with the 100uf capacitor connected to switch 1
  • Fuzz can be replaced with a fixed resistor of your choosing (1k - 2.2k as an example)
  • Pinch pot can be removed, connect the 100k resistor from base of Q1 to the blue jumper coming from the emitter of Q2.  Adjust the size to taste, bearing in mind that 100k is the standard Fuzz Face value

  • Completely remove the tone section and switching - 10n capacitor to Volume pot 3, same as a regular Fuzz Face
