The Erbe-Verb is more than a collection of reverb algorithms or presets, it is a unique, modeless, continuously variable reverb algorithm with complete voltage control. Typical reverb types such as plate, room, hall, shimmer and others may be programmed by adjusting the knobs. The continuously variable algorithm allows for hybrid and unreal spaces to be found. Traveling between spaces is possible by modulating the algorithm or manually sweeping parameters. More than an end-of-chain effects unit, it's a whole new building block for modular synthesis.
