The Electro-Harmonix Epitome Multi-effects Pedal is the quintessence of guitar effects. This powerful digital multi-effect begins with the flawless polyphonic tracking of the Micro POG. Next is the Stereo Electric Mistress. Creamy stereo flanging and chorus weave and undulate for the richest modulations. Finally, the Holy Grail Plus wraps you in a silken shroud of luxurious reverb. Shimmer mode reroutes the effects chain for a heavenly modulated ambiance. Blend KnobIt controls the wet/dry from 100 percent dry to 100 percent wet. Amount KnobThe function of the AMOUNT knob changes with each REVERB mode. Sub Octave Knob and Octave Up KnobIt controls the output volume of the SUB OCTAVE signal. The Octave Up Knob controls the output volume of the OCTAVE Up signal. Shimmer SwitchIt enables SHIMMER mode, which changes the routing between each effect to produce a lush, shimmering reverb tone while keeping a dry initial attack. When SHIMMER mode is enabled, the Holy Grail Plus LED lights up green. If SHIMMER is disabled, the Holy Grail Plus LED will be red. Rate KnobThis knob controls the speed or rate of the LFO signal that modulates the flanger. It also controls the rate of the Chorus effect. R Output Jack and Reverb SwitchThis 1/4-Inch jack is the right effect output jack. The reverb switch chooses the reverb mode i.e., SPRING, HALL, ROOM, or FLERB. Mono/L Output JackThis 1/4-Inch is the main effect output jack when connected in mono and the left output when hooked up in stereo. Flanger Depth Knob and Chorus Depth KnobIt controls the amount of Flange that is mixed with the direct signal. The Chorus Depth Knob controls the amount of the chorus sound.
