Earthquaker Devices Black Ash User Manual
<<< Switching >>>
This device is true bypass and uses electronic relay-based switching. Audio will not pass
without power.
<<< Power Requirements >>>
• Current Draw: 20mA
• This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We
always recommend pedal-specic, 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 specic power supplies do not lter
dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
<<< Tech Specs >>>
• Input Impedance: 100K Ohm • Output Impedance: 22K Ohm
<<< Warranty >>>
This device has a limited lifetime warranty. If it breaks, we will x it. Should you encounter any
issues, please email info@earthquakerdevices.com.

OPERATION MANUAL
Welcome to your new EarthQuaker Devices® Black Ash™ Endangered Fuzz!
This limited-run special edition fuzz unit is one of only one-thousand-ve-hundred in existence.
The Black Ash is a fuzz/overdrive that takes some cues from the vintage 3-knob Tone Bender.
It uses a highly curated cache of rare and irreplaceable components including paper-in-oil
capacitors and NOS half-watt carbon composition resistors from Jamie Stillman’s personal
stash to light a re under this classic fuzz/drive with an explosive-yet-detailed treble response, a
sturdy midrange, and subterranean bass extension.
The three controls on the surface of the Black Ash are for Level, Fuzz, and Top. Level sets the
output volume with unity gain around 10 o’clock. Fuzz adj usts th e amo un t of gain from cooled - off
amp-like breakup at lower levels to scorching fuzz tones when cranked. The control labeled Top
works on frequencies between 2kHz and 10kHz to adjust how “forward” the guitar sits in the mix
and helps pair the Black Ash with different pickup types.
At lower To p settings, Black Ash takes on an organic, woody character that blankets the signal
in warmth like an ol’ Kentucky hug. As the Top is increased, new harmonics appear, and the
Black Ash gives a stiffer response with a sharper attack that can make humbuckers chime and
will make single-coils glisten like pearly dewdrops in the morning sun. We nd the Top control to
be most pronounced when used at lower Level and Fuzz settings with low-to-mid-output pickups
and a reasonably clean or edge-of-breakup amplier.
Each Black Ash is built one-at-a-time, the hard way, by hand by amateur dendrologists in the
arboretum of Akron, Ohio, USA.
