The VO-1 Vocoder is a unique, innovative effects pedal that puts the massive expressive power of the human voice in the hands of every guitarist and bassist. By simply singing or speaking into a connected microphone, you can change your tone with electronic voices, classic talk box sounds and many other tools while playing, making it a perfect match for modern music styles. You can even easily create large choral ensemble sounds without having to connect a microphone. When you play the VO-1, your guitar can literally "talk, sing and scream". This takes your sound to a level you could only dream of before.
