You hear that EVP, bud? It's the all new, extra spook-tacular, Ghost Echo
from beyond the void! The Ghost Echo is our spooky take on the haunted amp-top spring
reverberation units of yesteryear. This creepy analog/digital spring reverb emulation
machine boasts a terrifying 30ms – 150ms of pre-delay, controllable via the Attack
knob, for everything from a quick, rockabilly slapback, to viscous pools of ectoplasmic
reverberations. When playing staccato, you'll hear the tortured trails of the reverb,
resulting in more of a slapback, or echo sound. Legato playing will reveal a massive
ambient "depth" that fattens up the sound – and look out it's right behind you!
Phew, that was close. The Dwell control sets the length and thickness of the decay,
which is to say that it controls how long the disembodied spirits of notes no longer with us
float through the ether; at the maximum setting, it will decend into an infinite loop of self
oscillation. The Depth sets the intensity of the reverb, which you probably know as the
wet/dry mix, but we like to think of it more as how scary the overall effect is.
The Ghost Echo is true bypass and built one at a time by a team of friendly ghosts in the
never-ending hall of funhouse mirrors that is Akron, Ohio, USA.
Controls
Attack: Adjusts the length of the pre-delay, from 30ms at minimum to about 150ms
at maximum. When the Dwell is set to self-oscillate, this will change the pitch of the
oscillations.
Dwell: Adjusts the length of the decay. This will start to self oscillate around 3 o'clock. The
pitch of the oscillations can be changed by turning the Attack control.
Depth: Mixes in the wet signal with the dry. Unity is around noon and everything after is
boosted.

® calling out Power
This device take 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!
Current Draw: 86 mA
Input Impedance: 10 MΩ
Output Impedance: 1 kΩ
Switching
This device is true bypass and uses electronic relay-based switching. Audio will not pass
without power.
Warranty
This device has a limited lifetime warranty. If it breaks, we will fix it. Should you encounter
any issues, please visit www.earthquakerdevices.com/warranty.
