Holy Grail

The Holy Grail Nano by Electro-Harmonix is a compact digital reverb guitar pedal that offers three different reverb algorithms: Spring, Hall, and Flerb. It faithfully emulates classic Spring reverb and provides lush spaciousness with the Hall reverb. The Flerb feature combines flanging with spatial reverb for a unique ethereal sound. The pedal is designed with a true bypass circuit and operates in mono audio. It comes with a 9.6VDC-200mA power adapter and has dimensions of 4.5 x 2.75 x 2.1 inches. The current draw is 105mA, and it was released in 2009. The pedal features a reverb selector switch, reverb knob, footswitch for engaging and disengaging the effect, input jack, and amp jack. The Holy Grail Nano has been praised for its authentic spring reverb sound and compact, affordable design.
