Electro-Harmonix Holy Grail Maxchat_bubble_outlineFrom real comments

Longtime Holy Grail fans feel right at home, with the Max adding welcome flexibility. Users who've used the original Holy Grail for years describe the Max as retaining that same beloved core sound while splitting the single reverb knob into separate Blend and Time controls. One commenter compared it favorably to their Fender Deluxe Reverb's onboard 'Flerb,' calling that built-in reverb terrible by comparison and returning to the Holy Grail sound instead.

The tone is called warm, thick and surprisingly analog-sounding despite being digital. One reviewer was impressed that the pedal delivers a warm, thick analog character even though it's not an analog reverb, and felt it outperformed fancier pedals costing twice as much. Others praised the pedal's overall character, calling it selective, fully wet-capable, long-decaying, and simply fun and inspiring to play.

Some technical quirks surface, particularly treble loss on the spring setting. One user reported that the spring reverb setting cuts a lot of treble from their signal, forcing them to boost treble on their amps to compensate, and asked if this was normal. Another asked whether the pedal suffers the same volume drop on wetter settings as the Holy Grail Nano, suggesting this is a known concern within the product line worth investigating before buying.
