Electro-Harmonix Holy Grail Nano

Electro-Harmonix · pedal

The Electro-Harmonix Holy Grail Nano is a compact, affordable digital reverb offering three algorithms, Spring, Hall, and Flerb. Its spring emulation is faithful enough to fool even surf legends, full of the drip and boing needed for classic combo-amp and surf tones, while the Hall mode is clean, warm, and spacious for lush ambience, and the Flerb mode combines flanging with reverb for a haunting, otherworldly spatial effect. The spring and hall voices have smooth tails and natural decay, and the pedal is prized for delivering excellent reverb quality and a sturdy build at a low price, which has made it many players choice over more expensive units. Simple to use with just a few controls, it suits surf, rock, indie, and ambient players who want straightforward, high-quality spring and hall reverb plus a creative modulated option in minimal pedalboard space.
