Electro Harmonix XO Holy Grail Plus · Guitar Effect

One of the most revered guitar reverb effects pedal has been reinvented with the Electro-Harmonix XO Holy Grail Plus!

The Electro-Harmonix Holy Grail pedal has been the guitarist's choice for reverb. The Holy Grail Plus Pedal from Electro-Harmonix adds room reverb and a multifunction decay / damping / modulation speed control.

The Electro-Harmonix Holy Grail Plus reverb pedal adds an AMOUNT knob to the reverbs found in the Holy Grail and Holier Grail: spring, hall, room and flerb. The Flerb reverb effect is made up of a reverb followed in series by a flanger.

With the Spring reverb the AMOUNT knob adds Spring Time/Reverb Time, with Hall AMOUNT adds reverb time, with Room changes the damping amount, and with Flerb changes the Modulation Rate/Flanger Feedback.

The Electro-Harmonix Holy Grail Plus is power by the included AC adapter.

Electro Harmonix XO
Electro Harmonix has packed many of his classics in a pedalboard friendly compact housing. So the legendary Electro Harmonix sound can also find space, even on notoriously overloaded effect boards .
