The Mooer R7 Reverb is a digital reverb pedal from the updated Micro Series. Based on a new set of unique reverb algorithms, the R7 combines seven types of reverb effects (Room, Hall, Church, Cave, Plate, Spring, Mod) in one small package. High- and Low-Cut controls allow users to trim redundant frequencies and shape the tone freely. The Decay and Pre-Delay controls adjust the characteristics of the reverb effect while the built-in trail functions can be switched between normal mode and 'Trail On' mode to allow effects to fade out naturally. Of course, each effect’s settings can be saved using the different preset slots so you never need to worry about losing that perfect tone!
