Black Ash Endangered Fuzz
  • Limited to 1,500 units
  • Uses rare and irreplaceable components from Jamie Stillman’s personal stash including paper-in-oil capacitors and NOS half-watt carbon composition resistors
  • Unique Top control adjusts key frequencies between 2kHz and 10kHz to adjust how “forward” the guitar sits in a full-band mix and helps to pair Black Ash with different pickup types
  • Volume control voiced for unity gain around 10 o’clock; lots of output on tap
  • Fuzz control adjusts gain from cooled-off amp-like breakup to scorching fuzz
  • True bypass
  • Silent relay-based switching
  • All-analog signal path
  • Lifetime guarantee
  • Current Draw: 20ma
  • Input Impedance: 100K
  • Output Impedance: 22K


This device is true bypass and uses electronic relay-based switching. Audio will not pass without power.


This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!


  1. Fuzz: Adjusts the amount of gain. Counterclockwise for less fuzz, clockwise for more fuzz.

  2. Top: Adjusts high frequencies between 2kHz - 10kHz and controls how “forward” the guitar sits in the mix. Counterclockwise for less top, clockwise for more top.

  3. Level: Sets the output volume. Counterclockwise is quiet, clockwise is loud.
