HOLY GRAIL PLUS
Reverb Pedal
Congratulations on your purchase of the Holy Grail Plus. The Holy Grail Plus starts
with the sounds found in the Holy Grail and Holier Grail: Spring, Hall, Room and
lerb. An AMOUNT knob has been added to give the musician further control over the
reverbs.
- EFFECT DESCRIPTIONS -
SPRING REVERB
The Spring Reverb effect is a simulation of the spring reverb found in many classic
guitar amps. In SPRING mode, the AMOUNT knob controls the size of the spring
reverb. The further you turn the AMOUNT knob clockwise, the bigger the spring
reverb will be. Set the AMOUNT knob to 3 o’clock to obtain the Spring Reverb found
in the Holy Grail.
HALL REVERB
Hall Reverb is a simulation of the reverb heard in a large space In HALL mode, the
AMOUNT knob controls the reverb time. The further you turn the AMOUNT knob
clockwise, the longer the reverb time and the larger the reverb space. Using the
AMOUNT control you can obtain reverb spaces from a room to a large hall. To obtain
the Hall Reverb sound found in the Holy Grail, turn the AMOUNT knob to 4 o’clock.
ROOM REVERB
Room Reverb is a simulation of the reverb heard in a small space. In ROOM mode,
the AMOUNT knob controls the damping factor of the reverb. As the AMOUNT knob is
turned clockwise, the reverb will be less damped. Set the AMOUNT knob to its
minimum position (full counter-clockwise) and the reverb will be heavily damped,
sounding like a bathtub reverb. Turn the AMOUNT knob to full clockwise and the
reverb sounds like an open room with no damping.
WARNING
Use only the 9.6VDC/200mA AC adapter the Holy Grail + comes
supplied with. Do not use any other AC adapters. Using other AC adapters, even
those made by Electro-Harmonix, could cause harm to the unit, the adapter or you.
The Holy Grail + does not use batteries.

FLERB REVERB
The lerb Reverb effect is made up of a reverb followed in series by a flanger. In
LERB mode, the AMOUNT knob controls the rate of the lerb’s modulation. As you
turn AMOUNT clockwise, the rate of modulation increases. To obtain the lerb sound
found in the Holy Grail, turn the AMOUNT knob to 8 o’clock.
