About Boss Vocoder

An innovative and unique stompbox, the VO-1 Vocoder revolutionizes the way guitarists and bassists express themselves through their instruments. This cutting-edge device harnesses the vast expressive range of the human voice, transforming your guitar or bass tone with electronic voices, classic talk box sounds, and a plethora of fresh tones perfect for contemporary music styles.

The VO-1 Vocoder allows musicians to create impressive ensemble vocal sounds without the need for an external mic. By simply plugging into the VO-1, you can talk, sing, and cry with your instrument, unlocking new dimensions of creativity and expression in your playing.

The human voice, with its ability to produce an extensive range of sounds, is undoubtedly the most expressive instrument. The VO-1 Vocoder's technology allows you to tap into this power, manipulating your instrument's tone in real-time to achieve speech-like sounds, infinitely controllable wah, and much more. This device brings the vocoder, a tool traditionally used by keyboardists to create electronic vocal tones and voice-like textures, within the reach of guitarists and bassists.

The VO-1 Vocoder simplifies the use of vocoder technology. It connects to your rig like any other pedal, requiring only a microphone to drive its vocoder engine in the first three modes. Once connected, simply activate the effect, adjust the knobs, and vocalize into the mic as you play. The VO-1 applies the complex formant characteristics of your voice to your tone in real-time, while you control the pitch as usual with your hands. The device also features an effect loop for integrating external effects and a Blend knob for mixing vocoder and straight tones.

Powered by BOSS' renowned guitar synth technology, the VO-1 Vocoder offers unparalleled power and versatility. Its Vintage mode delivers the familiar synthesized voice sounds found in numerous pop and electronic music records, while the Advanced mode uses new BOSS technology to translate speech and other vocalizations to your instrument with exceptional definition and clarity. The Talk Box mode recreates classic "talking lead guitar" tones without the need for a traditional talk box rig and mouth tube, making these cool sounds more accessible and convenient. Lastly, the Choir mode produces rich, impressive vocal textures from a direct input, eliminating the need for a mic.

In summary, the VO-1 Vocoder is a compact stompbox that brings cutting-edge vocoder technology to guitarists and bassists, opening up a world of new expressive possibilities.
