A company staple for over three decades, the Electro-Harmonix Holy Grail is one of those pedals everyone should play around with at some point. In 30+ years of production, the Holy Grail's evolved from its classic big box Spring/Hall/Flerb mode chassis into the sleeker Nano or Neo models and picked up a few new tricks in the Plus version. This reverb's become such a company standard that it even found its way into some EHX multi-effect monsters like the Epitome and Holy Stain. Found on the pedalboards of Radiohead, Spoon, Grizzly Bear and countless other bands, the Holy Grail offers the tone you've been seeking.
