B2, the third in 2CAudio's line of reverbs and spatial processors, is a modular dual-engine, non-linear spatial processor featuring built-in harmonic distortion and flexible dynamics. It is 2CAudio's most advanced plug-in to date and is capable of both "mind-bending creative effects that defy classification" as well as "stunningly lush" reverbs. Its modular design enables an almost infinite variety of sonic possibilities.
