Function F(x) Clusterfuzz

This Fuzz Friday I present you the Clusterfuzz from good dudes at Function F(x). It's a great sounding fuzz and really versatile. You might be able to squeeze this into a 125B if you can squeeze the rotary and toggle switches under the board. Otherwise a 1590BB like the original is probably the way to go.


  1. I'm really excited to build this but I can't find the Transfer Image dropbox.

  2. verified! Resistor 2k in the collector Q2 should be 10-22k, according schem there is 10k. 2k - not enough for good sustain & fuzz!Q1 used mpsa 14, working good.Instead rotary switch i used 2 SPDT.

    1. Yup, that resistor should be 10k as per the schematic link.thanks vit zzoyd .With 2k there is hardly any signal in my build . Used a 50k multitrim.

  3. Great pedal,very versatile. Thank you for this layout. Excellent forum

  4. Hi! Can i get principial shema? please.

  5. Hello, rookie question, how can i increase the “8-bit” effect??
