The inspiration for The Cloak came from the land of academia and the acoustics department at Stanford, where a treatise on the optimal shimmer effect was penned a handful of years back. In a similar pursuit of perfection, Catalinbread has drawn inspiration from a combination of research and their own endeavors to craft a truly superb take on shimmer reverb. At its core, the Cloak is a “room” style reverb that sounds amazing on its own, but with a twist of the Shimmer knob, rich, harmonically-laden overtones creep in, emphasizing three different orders of harmonics within the trails. A specially-designed low-pass filter steps in and smooths the harmonics out before they get too out of hand and wreck up the signal path. The size of the room can be effortlessly dialed in, from a cramped broom closet to as close to infinity as we can possibly muster. This comes in handy when deciding on which type of switching you prefer; the Cloak offers up true bypass switching that cuts off the reverb trails when the Cloak is disengaged, or buffered bypass, which keeps the decay going even after switching off—your pick. Either way you slice it, the Cloak is ready to impart a little black magic unto your rig.
The Cloak runs from 9 to 18 volts using a standard DC center-negative power supply for pedals. Make sure you’re using a supply that provides at least 100mA. 9 volts will sound great all around. But if you want even more output and an even healthier boost to your dry signal with increased headroom, try all the way up to 18 volts! The Cloak does not run on batteries.
The Cloak from has been given the Premier Gear Award –– they call it "An über-simple reverb whose sounds are both addictively immersive and impressively diverse." Read the full review here: Catalinbread Cloak Shimmer Reverb Pedal Review - Premier Guitar
