EarthQuaker Devices ⋅ Dispatch Master ⋅ Product manual ⋅ English ⋅ 🇬🇧
To use both effects at the same time, simply adjust all controls to taste:
- Mix
-
The Mix control is a wet/dry blend that adjusts the overall level of the affected signal.
- Time
-
Use the Time to adjust the delay time from 0 ms to 1500 ms (1.5 seconds).
- Reverb
-
Use the Reverb control to adjust the amount of reverb. Counterclockwise is less reverb, clockwise is more reverb.
- Repeats
-
Use the Repeats control to adjust the regeneration of the delay signal. When the Repeats control is set to maximum, you’ll get infinite repeats without runaway self-oscillation, which makes it great for creating drones, dialing in the ultimate post-rock guitar sound without feedback, or just having fun.
Using the Dispatch Master as a Delay only
Turn the Reverb control all the way down.
Adjust the Time, Repeats, and Mix controls to taste.

Pro Tip
In Reverb-only mode, the Repeats control has a secondary function. It can be used to adjust the decay, depth, and tonal quality of the reverb! Turn it up for more dynamics and a thicker tone.
Flexi-Switch® Technology
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 a signal.
Power supply
This device takes a standard 9-volt DC power supply with a 2.1-millimeter negative center barrel. We recommend using a pedal-specific, transformer-isolated wall-wart power supply or a power supply with multiple isolated outputs. Pedals will produce extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not always filter dirty power and may result in unwanted noise.
Do not run this pedal at higher voltages!
