*Not actually haunted. Or are they?

Controls:

1. 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.

2. 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.

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

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!
