We're happy to present the Kultrumm U73 based on the TAB U73, a German valve compressor of superlative quality.

Compression is produced by the action of two pentodes that attack the signal in tandem, easily obtaining powerful gain reduction with very low distortion. This version has high audio quality tubes, Brimar, Telefunken and Valvo.
