• Amazon: Electro-Harmonix Holier Grail Reverb
• Pros: A tweakable Gate setting, in a well-built pedal.
• Cons: A discontinued unit, with limited versatility compared to modern pedals.
• Overall: A cool, previously top-of-the-line, now out-of-production pedal.
As of this date, the Electro-Harmonix Holier Grail Reverb pedal has been discontinued. It was the top-of-the-line EH reverb pedal, before the Cathedral. But the Holier Grail has some cool features, that were left off the Cathedral…
One missing feature from the Cathedral is dynamic ducking. The Holier Grail has it, along with mono in/out. It also has a reverb-only out, which is unusual and pretty awesome. There’s a Gate setting with adjustable threshold (selecting the volume the gate is activated) you can use, over any of the 4 types of reverb (Spring, Room, Hall, and Flerb). The unit also has reversible dynamic ducking that works with your pick attack, so if you pick hard the reverb activates, and doesn’t when you pick lightly. You can also reverse the effect, and get some really ass-kicking sounds! I actually preferred it set in reverse, so the light picking gets reverb and the harder stuff doesn’t…give it a try. The gate also sounds spectacular with other instruments, like keyboards and drum machines. There are Length and Blend knobs that can adjust the mix of the reverb, and 2 Lengths: short and long.
It’s well worth digging around for the Holier Grail. If you unearth one, don’t be surprised if the clouds part and the Gods of Rock reach down out of the skies, and high-five you!
