Professor’s Notes

A true modern classic, the Holy Grail delivers three essential reverb types — Spring, Hall, and Flerb — in an easy-to-use, all-analog-style digital pedal. For players who want lush ambience without the complexity or cost of larger units, it’s the go-to value reverb.

Description

The Electro-Harmonix Holy Grail has earned its reputation as one of the most straightforward and musical compact reverb pedals ever made. With a simple control layout — a single Reverb knob and a 3-way mode switch — it covers a wide range of space-filling effects:

• Spring: Classic splash and bounce, perfect for surf or vintage-inspired tones.
• Hall: Expansive, lush reverb for ambient textures or live spaces.
• Flerb: A quirky, modulated reverb unique to EHX, offering experimental soundscapes.

Where boutique reverbs and larger digital units can overwhelm with options, the Holy Grail keeps things streamlined, musical, and affordable. Its compact footprint, rugged build, and true bypass switching make it equally at home on a beginner’s first board or a pro’s touring rig.

For guitarists seeking a dependable, characterful reverb pedal without breaking the bank, the Holy Grail remains one of the most trusted names in the game.
