The Black Finger is an optoisolator photocell, dual vacuum tube-based compressor. This means that the Black Finger uses the same professional-grade techniques that the most revered, vintage and mega-thousand dollar, high-end studio compressors use, except that it's in the form of an compact foot pedal.
Two different light sources (LED and Lamp) provide distinctly different readings and offer uniquely varied compressions. One tube handles the compression stage while the other manages the gain stage. And the Black Finger's design allows a full 300 volts of swing to be utilized. This makes it a true tube compressor in every sense. Whether used as part of an effects loop or with direct guitar, bass or voice, the Black Finger will breathe life and warmth into any musical instrument or recording. List Price $298.00 ea
