Electro-Harmonix Holy Grail Max Reverb Pedal

Gearank Recommendation

The Holy Grail Max appeared in the very first edition of our recommended list for Reverb Pedals from October 2016 until October 2018 and was removed when it was out-ranked by other reverb pedals.


The Holy Grail Max is part of Electro-Harmonix popular line of reverb pedals, with this one carrying a few more features for sonic versatility while still keeping the interface and control options within old school territory.

For a pedal with a wide palette of reverb sounds, this pedal features a simplistic set of controls that allow for reverb type switching, and adjustments for the time and blend parameters.

Red Hot Chilli Peppers' Josh Klinghoffer has been seen using this pedal to lay down the complex and funky guitar lines that his band requires.
