<<< Tech Specs >>>

• Current Draw: 10mA

• 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: 50K Ohm • Output Impedance: <10K 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.

<<< Flexi-Switching >>>

This device features Flexi-Switch

™

Technology! This relay-based, true bypass switching style

allows you to simultaneously use momentary and latching-style switching.

• For standard latching operation, tap the footswitch once to activate the effect and then tap

again to bypass.

• For momentary operation, hold the footswitch down for as long as you’d like to use the effect.

Once you release the switch, the effect will be bypassed.

Since the switching is relay-based, it requires power to pass signal.
