<<< Power Requirements >>>
<<< Tech Specs >>>
• Current Draw: 86mA
• This device take a standard 9 volt DC power supply with a 2.1mm negative center barrel. We
always recommend pedal-specic, 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 specic power supplies do not lter
dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
• Input Impedance: 10M Ohm • Output Impedance: 1K Ohm
<<< Warranty >>>
This device has a limited lifetime warranty. If it breaks, we will x it. Should you encounter any
issues, please email [e-mail].

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

<<< 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.

You hear t hat E V P, bud? It’s th e al l ne w, ex t r a sp o o k-tac u lar, Ghost Ec h o™ calling out 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 (1) 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 (2) 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 oat through
the ether. At the maximum setting it will descend into an innite loop of self oscillation. The
Depth (3) control 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.

<<< Suggested Settings >>>
Mellotron Strings
Perfect for volume swells and for, of course, the
mighty Mellotron.
Upstroke Reverb
Perfect space for four chord upstrokes and for
that classic pre-delayed reverb presence.
Motion Vapers
Add some sonic breeze to those climbing
single note runs.
