The Holy Grail is Digital Reverb in a compact guitar pedal. It contains three different reverb algorithms: SPRING, HALL, and FLERB. All three algorithms were designed and tailored for the electric guitar but they will work equally as well on most instruments and voices. The SPRING algorithm is a recreation of the classic spring reverbs that are found in many guitar amplifiers. The HALL algorithm is a new, lush reverb. Finally FLERB is a beautiful reverb like nothing you have heard before and may help you play your instruments in new ways.
-THEORY OF OPERATION-
Connect your instrument into the INPUT jack and your amp into the OUTPUT jack. Plug the DC adaptor into the US96DC-200BI jack and then plug the DC adaptor into a wall outlet.
The STATUS LED indicates when the effect is switched on. The footswitch engages and disengages the Reverb effect.
The REVERB knob acts like a Wet/Dry control. As you turn the REVERB knob clockwise you will hear more reverb and less of your dry instrument. The Holy Grail is designed so that as you turn the REVERB knob from its minimum position to the 12 o’clock position you will hear a subtle amount of reverb added to the output. As you turn the REVERB knob from 12 o’clock to its maximum position the amount of reverb you hear will increase dramatically. It is designed this way so musicians can hone in on just the right amount of subtle reverb added to their instrument’s signal. The Slide Switch chooses between the three different reverb algorithms. The Slide Switch chooses between the three different reverb algorithms.

I used to add true bypass to these, so that when OFF there is no digital noise or change in tone. But later models of these pedals came from EH with true bypass switches already installed.
