The WA-1B accurately recreates world-class Scandinavian compression, sombining smooth tube-optical warmth with precision controls. Like its original inspiration, favored by producers and engineers from Chris Lord-Alge to Rick Rubin, the WA-1B delivers that revered forgiving musical compression of tube-optical circuitry with speed and control more closely associated with modern dynamics processing. Hand-wired to authentically recreate the sound of a renowned circuit, the WA-1B combines custom large-core transformers from Ludahl Sweden, select tubes from JJ and Tung-Sol, and a premium high-precision optical element for ultra-fast and accurate operation without sacrificing authentic analog warmth.

Hardware processing that stays out of the CPU.
