MXR M309 Joshua Ambient Echo

The MXR Joshua Ambient Echo is a one-stop-shop sunk deep into iconic soundscapes, from tonal trips out of the ’60s and ’70s to the ethereal ambience of the ’80s. Once upon a time, you needed a whole rack processor get these tones, but this pedal comes with everything you need to cop that distinct tonal palette in a modern and user-friendly format—and it’s already dialed in and ready to go.

The MXR Joshua Ambient Echo is built on a foundation of meticulously tuned tones and textures that combine to encapsulate the rich, atmospheric essence and grand sense of space that have been the hallmark of countless classic tracks. It all comes baked in—all you have to do is season to taste, and transcend the sonic stratosphere.

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 disengaged? 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 ambience already crafted by the pedal’s other elements for a truly otherworldly sonic experience.

The MXR Joshua Ambient Echo comes carefully tuned to achieve atmospheric brilliance right out of the box without much tweaking on your end—but if you feel that siren’s call for further sonic exploration, then this pedal has all the tools you need to shape complex custom soundscapes. Along with stereo and expression pedal capability, you can adjust up to 12 different parameters—from how the LEDs flash to the mix of the secondary echo signal.

The MXR Joshua Ambient Echo isn’t just a delay—it’s a tonal recipe expertly concocted for those who seek atmospheric perfection. Whether you're an ambient rock enthusiast or a tonal architect, this pedal is your ticket to iconic sonic sanctuaries.
