BOSS's VO-1 Vocoder Pedal combines a vocal synth and a talk box into a stompbox chassis. Using the onboard XLR microphone input, plug in a microphone, and vocally modulate your guitar's signal using one of the synth or talk box modes. This cool effect is not just for guitars. Plug in your bass or a synth and see what other cool tones you can achieve.
Laid out in the familiar BOSS style, the VO-1 is intuitive to operate. The concentric Level and Blend controls adjust the output and balance between the wet and dry signals, respectively. Tone and Color controls offer general adjustment of your sound. The Mode knob selects what kind of synthesis the pedal applies to your guitar's signal
Vintage Mode: produces familiar synthesized voice sounds heard on pop and electronic music records throughout the years
Advanced Mode: utilizes new BOSS technology to translate speech and other vocalizations to your guitar's sound with more definition and clarity than the Vintage mode
Talk Box Mode: recreates the classic "talking guitar solo" without complex or finicky traditional mouth-tube rigs
Choir Mode: produces vocal textures just based on your guitar's input, no mic is required
XLR Microphone Input
Instead of relying on mouth tubes or other setups for vocal capture, the VO-1 uses a standard XLR microphone input. The sensitivity can be set at either low or high using the switch near the power input at the top of the pedal
A second set of I/O is offered to add effects to the VO-1's signal path. Put some delay, distortion, or modulation effects in the loop for quick activation when the VO-1 is engaged. These effects will only be in your guitar's signal chain while the VO-1 is active
Classic BOSS Design
The VO-1 can run off of a single 9V battery or an optional external 9 VDC power supply. The electronics are encased in BOSS's iconic durable metal housing with a non-slip rubber base, and the battery compartment can be easily accessed by unscrewing the thumbscrew at the front of the pedal. This pedal utilizes a buffered bypass for silent switching and driving long cable runs, even while the pedal is disengaged.
