Dunlop announced the launch of the MXR Joshua Ambient Echo on 2 January 2024, a stereo delay pedal that the maker says draws on classic studio rack effects12.
The pedal has six knobs: Delay, Modulation, Voice, Regen, Division and Mix, plus Echo 2 and Trails buttons34. The Delay knob sets echo timing from 50ms to 1000ms2. The Division control offers five subdivisions: quarter note, dotted eighth, eighth, eighth triplet, and eighth plus dotted eighth25. The Voice control sweeps a blend of polyphonic octave signals from -1 to +223. Echo 2 adds a second set of repeats, and Trails lets echoes fade after the pedal is switched off21. There is onboard tap tempo via the footswitch and a CTR jack for an expression pedal12. Guitar.com reports up to 12 adjustable parameters, including the mix of the secondary echo signal1; Guitar Pedal X counts 18 parameters across six knobs and nine controls, with secondary functions on the knobs5. Guitar Pedal X gives the power requirement as 9VDC, 300mA5.
Guitar.com describes the enclosure as Phase 90-sized1. Guitar Pedal X reports full stereo ins and outs via TRS cables5.
MXR describes the pedal as:
"a tonal recipe expertly concocted for those who seek atmospheric perfection"
Pricing is reported differently. MusicRadar gives $239.99 at Sweetwater and Guitar Center3; GuitarPlayer says it is available now for $2394; Guitar Pedal X lists $2405. Guitar.com, publishing on 3 January, said pricing was yet to be revealed1. Dunlop's own site lists the M309 at $169.99 alongside a second figure of $255.9967.
