The HummingVerb it's a digital reverb with three modes: Classic, Hall and Shimmer, two external controls: Blend and Decay and two internal controls: Output Volume and Input Volume. The Classic mode provides an non invasive reverb with fair amount of decay, it’s ideal to leave it on all the time. The Hall mode it’s a more complex, dense and modulated reverb with tons of decay (can be infinite with the decay control maxed out) so you can do drones and pads with it. The Shimmer mode adds regenerated up octaves with no limits!, between the decay control and your playing dynamics you can control how many octaves are generated. All the modes are extremely lush and dynamic, your playing can control the depth of the reverb, giving you maximum expression. The Analog Dry-Through circuitry keeps your instrument's dry tone intact. Like all the MBS pedals it's built with top quality components and True Bypass switching system with a stage-ready status LED, preserving your instrument's tone when it's not engaged.
