The Mooer Audio R7 X2 Reverb takes Mooer's best digital effects algorithms from the A7 Ambiance and R7 Reverb pedals and combines them in to one ultimate stereo reverb pedal. Parameter knobs include High Cut, Low Cut, and Mix for adjusting the EQ and Decay and Pre-Delay knobs for adjusting the intensity of each effect. Unique features of the R7 X2 include the Infinite and Trail-on functions to customize how each effect fades out. The pedal features a single designated save slot for each effect where users can save their settings after being tweaked to perfection.
