The Holy Grail Plus is a digital reverb pedal built on the original Holy Grail's spring, hall and flerb reverbs, with an added room mode. A four-position Reverb switch selects the mode, and a Blend knob sets the wet/dry mix from fully dry to fully wet.
The Amount knob changes function depending on the selected reverb mode, giving control over decay, damping and modulation speed. A status LED shows when the effect is active, and a footswitch toggles it on and off. The pedal uses true bypass, so the signal path is untouched when the effect is off.
Connections are a single 1/4" input and a single 1/4" output for mono operation. The pedal sits in a compact die-cast chassis and runs from the supplied 9.6VDC, 200mA power adapter, drawing 190mA. It was released in 2008 and discontinued in 2022.
