MXR M309 Joshua Ambient Echo Effect Pedal

The MXR Joshua Ambient Echo is your ticket to iconic sonic sanctuaries, featuring a foundation of carefully concocted tones and textures, highly customizable delay, and other features to help you craft soundscapes worthy of tonal trips out of the ’60s and ’70s and ethereal ambience from the ’80s.

This pedal requires 9 volts (300mA) and can be powered by the Dunlop ECB003 9-volt adapter or the MXR Iso-Brick Pro, Iso-Brick, and Mini Iso-Brick power supplies. This pedal cannot be powered by a battery.

The core of the MXR Joshua Ambient Echo is its highly customizable delay setup, offering control over not only the tempo and number of echoes—Delay and Regen controls—but also their rhythm. With a turn of the Division control, you can select from ¼ note, dotted ⅛ note, ⅛ note, ⅛ note triplet, double delay with an ⅛ note, and dotted ⅛ note subdivisions. Want your echoes to keep trailing off even after the pedal disengages? Just push the Trails. Want an even more dynamic sound? The Echo 2 switch adds a secondary set of echoes set to 1/4 note tempo—which can be adjusted through advanced settings.

For direct control over the timing of your echoes, this pedal supports both onboard tap tempo through the footswitch and off-board switching through the CTR jack. An off-board switch also allows you to freeze your delay lines at max feedback so that you can weave leads and solos over your tonal tapestry.

With the MXR Joshua Ambient Echo, refining the tones and textures of your echoes is effortlessly intuitive. The Mod control washes your delay signal with lush, chewy modulation. Once that’s dialed in, elevate the entire soundscape to celestial heights with the Voice control. It conjures an angelic, organ-like aura through a custom mix of -1 sub-octave, +1 octave up, and +2 octave up signals, amplifying the ethereal ambiance already crafted by the pedal’s other elements for a truly otherworldly sonic experience.
