Electro Harmonix DIGITAL FOOT REVERB

(This text is machine translated) Holy Grail is a compact digital reverb. Contains three different Spring, Hall and Flerb reverb algorithms. All algorithms have been custom designed for the electric guitar, but work just as well on other instruments or vocals. The Spring algorithm is a recreation of the classic reverbs found in many guitar amps. The Hall algorithm is a lush new reverb. Finally, Flerb, is a reverb like you've never heard before: you will hear your instruments playing in a new way.
