R7 - 

Digital Reverb

The MOOER R7 Digital Reverb pedal brings rich, classic reverb tones to The New Micro Series. Based on a brand-new set of unique reverb algorithms, the R7 packs 7 types of reverb effects from the “Church” to the “Cave”. High and Low Cut controls allow users to trim redundant frequencies and shape the tone freely, 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!
