This used EarthQuaker Devices Avalanche Run is in excellent condition and functions flawlessly. The Avalanche Run is a powerful stereo delay and reverb workstation, capable of everything from pristine rhythmic echoes to massive ambient soundscapes, reverse textures, and volume swells. With up to just under 2000ms of delay time, lush reverb, tap tempo, and deep expression control, it’s a favorite among players who want both traditional and experimental effects in one premium pedal.

The delay section features intuitive controls for Time, Repeats, Tone, and Mix, allowing you to go from subtle slapback to near-infinite repeats, with the ability to sculpt the delay tone from dark and warm to bright and cutting. The reverb side offers its own dedicated Decay and Mix controls, capable of everything from short room ambience to huge, cavernous washes.

The three-position Mode toggle lets you switch between Normal, Reverse delay, and Swell modes, while the Ratio selector offers multiple rhythmic subdivisions for tap-tempo use, including quarter notes, dotted eighths, triplets, and sixteenths. An onboard expression system allows control over Time, Repeats, Delay Mix, Reverb Mix, Decay, or even cross-fading between forward and reverse delay—unlocking dramatic pitch dives, oscillations, and evolving ambient effects that go far beyond standard knob adjustments.
