Electro-Harmonix NEO HOLY GRAIL User Manual

NEO HOLY GRAIL
Congratulations on your purchase of the Neo Holy Grail, an update to our wildly popular
compact digital reverb, the Holy Grail. It contains three reverb algorithms: SPRING, HALL,
and PLATE. All three algorithms were designed and tailored for the electric guitar but they
work equally well on most instruments and voices. The SPRING algorithm is a re-creation
of the classic spring reverbs that are found in many guitar amplifiers. The HALL algorithm
simulates the reverberations heard in large spaces such as a concert hall or cathedral. The
PLATE algorithm is an emulation of a metal plate reverb commonly found in high end
recording studios during the 1960s and '70s. The PLATE reverb is a very smooth, tonally
balanced sounding reverb that sounds great on many different instruments, especially
vocals. True bypass switching ensures your tone won't be affected when the pedal is
bypassed.
CONTROLS
REVERB Knob – Controls the wet/dry mix from 100% dry (counter-clockwise position) to
100% wet (clockwise position). As the REVERB knob is turned, the overall output volume
remains nearly constant. Your dry signal remains analog from input to output through the
Neo Holy Grail.
Toggle Switch – Switches between the three different reverb algorithms.
INPUT Jack – This ¼" jack is the audio input of the Neo Holy Grail. The input impedance
is 1MΩ.
AMP Jack – This ¼" jack is the audio output of the Neo Holy Grail. The output impedance
is 500Ω.
WARNING: Your Neo Holy Grail comes equipped with an Electro-Harmonix 9.6DC-200BI
power supply (same as used by Boss ® & Ibanez ® : 9.6 Volts DC 200mA). The Neo Holy
Grail requires 75mA at 9VDC with a center negative plug. Using the wrong adapter may
damage your unit and void the warranty.
