The MXR Joshua Ambient Echo stands out for its ability to generate an impressive array of echo tones. Whether you’re aiming for psychedelic effects or an ethereal ambient rock vibe, this pedal has got you covered. Its creators have described it as more than just a delay pedal; it’s an expertly crafted tool for achieving atmospheric perfection.

Ideally, MXR could have released it on New Year’s Day… However, NAMM 2024 looks to be the actual release schedule for this new pedal.

One intriguing aspect of the Joshua Ambient Echo is its potential connection to U2’s iconic album, “The Joshua Tree,” particularly the distinctive delay tones used by the band’s guitarist, The Edge. MXR acknowledges that this pedal is inspired by vintage rack-style units similar to those The Edge might have used, adding a touch of rock history to its appeal.


The pedal offers a robust set of controls, including knobs for Delay, Modulation, Voice, Regeneration, Division, and Mix, as well as Echo 2 and Trail buttons. These features allow users to precisely tailor the tempo, intensity, and character of the delays. The Division control offers five distinct delay patterns, and the Delay knob adjusts the timing of echoes from 50ms to 1000ms. The Voice control blends in polyphonic octave signals for additional tonal variety.
