Holiest Grail

Programmable Stereo Reverb
(Note: The Holiest Grail is no longer available, please see our current lineup of reverb pedals.)
Supreme bliss! The Holiest Grail lives up to its name by being the loftiest Grail product yet. Carve out your own private paradise by tailoring the length and sound of your reverb using a customizable pre-delay and decay time, then add feedback or adjust damping and diffusion. Recall up to eight custom presets that transport you to sonic extremes, or mix Spring and Hall reverbs together just because you can. Use the Holiest Grail as a MIDI controller with the option of adding external control for managing the sliders and loading presets. Heaven never sounded so good.

Welcome to the fifth installment of EHX Effectology. In today’s episode Genius sound producer Bill Ruppert has produced another amazing “Effectology” sound clip. Using only Electro-Harmonix pedals and NO synthesizers, Bill recreated of Kraftwerks’s classic “Autobahn.“

Please note: Bill will be in the EHX Forums to discuss his sounds, settings, and process. We hope you join us there.

Welcome to Electro-Harmonix's new "Effectology" series. Over the next several months we're going to play a remarkable collection of EHX-assisted sounds, and explain how they were made.

In the first episode, effect pedal wizard and Chicago studio musician Bill Ruppert transforms his regular electric guitar into a blues harmonica (pedals used: HOG, Micro Synthesizer, Wiggler, Holiest Grail).

Please note: Bill will also be in the EHX Forums to discuss his sounds, settings, and process. We hope you join us there.

The EHX Effectology series was originally inspired by Bill's recreation of the synth intro to The Who's "Won't Get Fooled Again" (see here). Stay tuned, more Effectology episodes coming soon!

We've been playing these EHX Strings ever since we first took them home to try them out, back in 2002.

We find them to consistently offer rich harmonics with powerful definition, while also lasting longer and staying in tune longer than conventional strings.

We use them, we like them, and we think you will too. Available in 9's, 10's, 11's.
