Earthquaker Devices Avalanche Run V2 

The EarthQuaker Devices Avalanche Run V2 is built with one goal in mind and this is to take the floating ambient tones of our Dispatch Master to the next level.

And still keeping it user-friendly and refined, because taking you into the aural exploratorium without having to break open the user manual every time you want to open up your inner eye and get free is no easy task.

We are using a high-powered proprietary DSP platform to recreate all the characteristics of all our old favorite delay and reverb machines while still retaining a simple, yet flexible workspace.

What is the EarthQuaker Devices Avalanche Run v2?

The Avalanche Run is a dreamy sonic discovery device with up to 2 seconds of delay time and a lush stereo reverb, so it gives great control

It features complete control over delay time, repeats, mix and voice (with the tone control), as well as control over the reverb length and mix.

There are lots of demos here.

Avalanche Run Modes

There are 3 different modes, Normal, Reverse and Swell.

While in Normal and Swell mode, you can send the Avalanche Run into self-oscillation by holding down the Tap footswitch.

In Reverse, mode holding down the Tap switch will flip the delay back into Normal mode and return to Reverse mode once released!


In “Normal” mode, the Avalanche Run is a straightforward delay and reverb.


In “Reverse” mode, the delay line is in reverse and the reverb remains in normal mode.


In “Swell” mode, the Avalanche Run reacts to your picking dynamics and adds a volume swell to the entire signal path much like, for instance, manually raising and lowering the volume of your guitar.

The Avalanche Run features an expression jack that can be assigned to one of six different controls using the EXP selector switch.

It also features Tap Tempo with six different ratios which are accessed via the Ratio selector switch.

It can also be run in True Bypass mode or Buffered Bypass mode for trails and features 5 different tail lengths including Infinite for lo-fi and continuously degrading pseudo-looping.

The Tap switch also has a few other cool secondary functions.



This controls the delay time and goes from 0ms to just under 2000ms.

It takes over from the delay time control and is drastically different than the interface control.

Using the expression pedal to control the time gives you all kinds of wild effects that can not be achieved by turning the knob.


Controls the regeneration of the delay and takes you from zero repeats to near infinite.


Controls the tone for the delay line only. Roll off highs to the left, roll off lows to the right, and get a flat response in the middle.


The is the volume control for the delay line which blends in the wet with dry.


Controls the reverb decay length giving short decay counterclockwise, long cavernous decay clockwise.

R Mix

Controls the reverb mix

D Mix

Controls the delay mix

Expression Jack Assign Switch

Use this switch to map the expression jack to one of the assigned controls.

Mode Selector Switch

Both: This is the “standard” delay and reverb model.

Reverb is fully stereo and follows delay in the signal path.

All controls work as displayed. When using tap tempo to set the delay time, the repeats are cleared once a new time is tapped in.

Hold Tap switch down to send delay into infinite repeats and on shorter time settings, they will quickly go into oscillation and on longer time settings, they will slowly build.

Reverse: This is reverse delay mode with “standard” reverb.

Reverse delay, normal reverb. Ratio is always in 1/1 position no matter where the ratio switch is set.


This is the volume swell mode which adds an auto swell to the entire signal path, much like slowly turning up the volume control on your guitar.

Reverb Mix controls the length of the swell, and swell length becomes longer as you turn the control clockwise.

Trigger swells from the input, regardless of input strength.

To get the most from this effect, adjust your playing to a more staccato style and mute the strings after every note or chord.

This mode sums both left and right inputs on both the wet and dry paths to mono.

Hold Tap switch down to send delay into infinite repeats.

On shorter Time settings, they will quickly go into oscillation and on longer Time settings, they will slowly build.

Set 5 different tails modes, allowing the wet signal to naturally fade.
