The BOSS VO-1 is a one-of-a-kind and ground-breaking vocoder pedal that puts the vast expressive range of the human voice in the hands of every guitarist and bassist. The tone is simple to change with electronic voices, vintage talk box sounds and hundreds of all-new colors that are suited for current music genres by vocalizing into a connected mic while playing. Also feasible is making powerful group vocal sounds without using an external microphone. When you connect your axe to the BOSS VO-1, you can practically talk, sing, and cry with it, pushing your playing to new heights.
