Product Information

Full details

The Electro-Harmonix Holy Grail Neo is a compact digital reverb effects pedal designed for guitarists seeking versatile and high-quality reverb sounds. Its key benefit lies in offering three distinct, studio-quality reverb algorithms in a pedalboard-friendly format. A minor caveat is its single-knob control for wet/dry mix, which may limit fine-tuning for some users. This pedal features Spring, Hall, and Plate reverb types, true bypass, and a robust metal chassis.

Troubleshooting

No sound or weak signal

Check all cable connections. Ensure the pedal is powered on and the correct power adapter is used. Verify that the effect is engaged (LED is lit).

Setup: Connect your instrument to the INPUT jack and your amplifier to the OUTPUT jack using standard 1/4-inch instrument cables. Plug in the included 9.6VDC-200mA power adapter to the power jack. Use the toggle switch to select between SPRING, HALL, or PLATE reverb. Adjust the REVERB knob to set the desired amount of effect.
