Holy Grail Reverb

Divine reverb for mere mortals. Down from the heavens comes the Holy Grail, a compact digital reverb guitar pedal that is priced so low thou shalt not covet thy neighbor's reverb tank any longer. The Holy Grail will make you a believer with its emulation of classic Spring reverb so faithful that even Dick Dale couldn't tell the difference. Next, get lost in the lush spaciousness of the Hall reverb and ask yourself, "how did they fit Notre Dame into such a small package?" Finally, reach enlightenment with the haunting Flerb.

Nancy Wilson and her sister Ann showed the world that women can rock when their band Heart first shot up the charts in the 1970s with a string of hits like “Crazy on You,” “Magic Man” and “Barracuda.” Now, with over 35,000,000 albums sold and the band’s induction into the Rock and Roll Hall of Fame, Nancy is still rocking.

In the July 2013 issue of Premier Guitar magazine, Nancy, described as a “Goddess of Rhythm,” talks about the journey and her gear. EHX is proud that Nancy uses a Holy Grail reverb and Small Stone phase shifter.

Be sure to catch John Frusciante's comments on the English Muff'n in the April 2009 issue of Vintage Guitar Magazine: "The Electro-Harmonix English Muff'n tube fuzz has some really extreme EQ and a big, thick and meaty sound. I used it on the solo for 'Enough Of Me.' I turn the EQ up, but leave my guitar tone knobs down and use either the middle or neck pickup so the original source sound is really dark and plain. If you blast the tone controls on the effect, you get a really thick, beautiful sound that reminds me of an exaggerated Eric Clapton tone in cream, where you have this really smooth fuzz."

In addition to the English Muff'n, John has also toured and recorded with the Micro Synthesizer, Big Muff Pi (both USA and Russian), POG, Metal Muff, HOG, Holy Grail, and Deluxe Electric Mistress. That said, I'm sure you fru-heads are still going to email and tell me what I left out.

Did you know that Electro-Harmonix makes many of the world's greatest vacuum tubes? The next time you need to re-tube your guitar, bass, or hi-fi amp, be sure to insist on getting authentic Electro-Harmonix tubes.
Our new EHX Strings Electro-Harmonix electric guitar strings are custom-designed to our specifications and made in the USA by a premiere string manufacturer. Each wound string is precision wrapped with round nickel-plated steel onto a high carbon, hexagon-shaped steel core. The plain strings are made from the same high carbon steel as the hex cores. The high quality steel and computer controlled winding process results in strings that intonate accurately, are better at staying in tune and vibrate evenly for maximum sustain.
Dig it, now you can rock EHX in our new heavy-duty black hoodie! It’s emblazoned with the iconic Electro-Harmonix Flashback logo in white on the left chest and back.
