January 12, 2024 · 3 sources

Mooer announced the Mooer Harmony X2, a stereo harmony and pitch-shifting pedal, in the run-up to NAMM 2024, alongside the Tender Octaver X21. Delicious Audio reported on the pedal on January 12, 20242; Guitar World covered both X2 Series pedals on January 15, 20241.
The pedal offers 12 pitch options covering the chromatic scale, each with major and minor scales, plus 11 harmony modes including thirds, fifths, sevenths and octaves31. Players can set separate harmonic intervals for the left and right outputs, each with its own volume dial, and a Dry dial sets the level of unprocessed signal32. Delicious Audio describes the left channel range as "anywhere from on octave up to a minus 6th" and the right as "anywhere from an octave down to a plus 6th"2. A dual footswitch toggles the left and right harmonies independently, and a Save button stores presets3. Delicious Audio reports a 7 preset system2; Mooer's page does not state a preset count3.
The pedal has two 1/4-inch inputs and two 1/4-inch outputs, with outputs supporting stereo mixed or individual modes31. Delicious Audio describes the routing as allowing a mono channel to feed the stereo effect or the two shifters to run in dual mono2.
