Once you start using the DigiTech DigiVerb Digital Reverb Pedal you won't want to stop. The spring reverb is so real you can almost hear the spring rattling in the box. Different plate reverbs put excitement in your snare or vocals, and various halls breathe warm space into any instrument sound. Level, EQ, Decay, and Type controls let you tailor your 'verb any way you like. Left/mono and right outputs.
