The Mooer Skyverb is spacious 32 bit digital reverb pedal that gives large cavernous sounds in a tiny pedalboard footprint. It has 3 reverb modes: Studio/ Church/ Plate Studio. Studio is a warm all purpose natural indoor reverb. Church reverb is big open natural reflex reverberation. Like it's name it sounds like you are playing in a big cavernous church. Great for spacey sounds. The Plate mode gives studio quality plate reverb of old. The decay knob gives you a large amount of reflection and the tone knob allows you to dial EQ the reverb.
