Product Overview
The Holy Grail Nano is a compact analog reverb and flanger pedal designed specifically for electric guitars. Housed in a sturdy black enclosure, it weighs just 10.6 ounces and measures 7.8 x 4.3 x 4.3 inches, making it ideal for tight pedalboards. Powered by a single 9V battery, the unit offers a smooth “hall” reverb and a distinctive “flerb” effect that combines flanging with spatial reverb for an ethereal sound. Its 1/4‑inch audio interface ensures seamless integration with any amp or rig.
