The JHS 3 Series Octave Reverb is the company's take on the classic Eno/Lanois shimmer effect. This stompbox delivers everything from sublime, hall-like ambience to swelling octave overtones, via intuitive, top-panel controls. The Octave Reverb enables you to dial in the size and intensity of your reverb via Verb and Decay knobs, while a third knob feeds the octave into your reverberated signal. An Up/Down switch toggles between +1 and -1 octaves, allowing you to achieve both symphonic shimmers and unique octave-down effects for your reverb tails. The 3 Series Octave Reverb offers a unique alternative to plain-vanilla reverbs. If you don't have a shimmer 'verb on your pedalboard, this budget-friendly guitar effect is an absolute no-brainer.
