Arbiter Fuzz Face Clone Schematic


  1. Steve Griffin says:

    Is there any reason the values on this schematic do NOT correspond with the BOM?
    Do these values make a different sounding Fuzz unit?
    Kind Regards,

    Hey Steve,
    The schematic was the original version. Due to part availability and other reasons, we changed them to whats in the bom. The different transistors will definitely cause some change in the tone.

    Please consider changing the PCB layout by adding a resistor between GND and the emitter of Q1. That would serve as a way to solve problem with the Q1 biasing with some randomly selected devices. It can be bypassed by zero ohm resistor if not needed.

    Thank you for the suggestion, next time we do a board revision on this, I’ll take a look into adding this resistor.
