The Pitch Bay is a three part polyphonic harmonizer and distortion generator in one compact enclosure. It features two voices of adjustable polyphonic pitch shifting, one above the root and one below. Each voice can be adjusted by stepped semitones, from 1 semitone to 12 semitones (one full octave) above and below the root. Each voice (Pitch up, Pitch down and Root) has an adjustable mix control so they can be blended, cut or boosted to your hearts desire. The Pitch Bay also features an adjustable input gain that goes from clean to heavily distorted to unleash your inner hesher. This device has an all analog adjustable gain preamp, all analog signal path for the root, all digital pitch shifting engine and true bypass switching for activation. Each Pitch Bay is made one at a time by hand in the private beach front resort sector of Akron Ohio. Controls Pitch Up: Selects the upper harmony, 12 semitones starting at 1 above the root.
