Gurus OptiValve · Guitar Effect

Optical tube compressors are considered the "non plus ultra" in studio technology when it comes to musical compression. The warm, pleasant sound of a vintage tube compressor is still unmatched. The Italian amp specialist Gurus also has a tube compressor in its floor effect line. The Optivalve not only convinces through its iconic appearance, but can also score with its sound. A very cool featureis the magic eye which acts as a control instrument.
