The compact Electro-Harmonix Holy Grail Nano pedal has those treasured Holy Grail reverb sounds, and features mono in and mono out, with true bypass switching.
The Electro-Harmonix Holy Grail Nano has the same prized sounds as the legendary Holy Grail reverb pedal, in a rugged, performance-friendly nano die-cast chassis that’s just a little over two inches wide. It’s designed to be very easy to use with only one switch and one control knob needed to dial in your reverb settings. The three-way switch toggles between the three different types of reverb available.
The first type is a Spring reverb emulator that perfectly recreates the classic spring reverb found in many amps. The next type is the Hall reverb, which is designed to sound lush and warm and put the sound in a bigger space. The third type of reverb is called Flerb and Electro-Harmonix designed this as a modern-sounding effect that blends flanger and reverb for a unique sound with a haunting spatial definition. The single Reverb control knob adjusts the amount of reverberation that is added to the signal.
This compact pedal features mono in and mono out, with true bypass switching. It’s too small for a 9-volt battery so the pedal runs on an external 9-volt power supply that is included with the unit.
