Boss VO-1 Vocoder
BOSS's VO-1 Vocoder pedal lets guitarists achieve vocal and synthesizer effects with their electric guitars. Four modes - Vintage, Advanced, Talk Box, and Choir - take your guitar tone from warm analog synth sounds to sounding like an army of harmonized guitars. Plug a microphone in and you can control the parameters with your own voice. And the onboard effects loop lets you get even more tonal options from your VO-1 Vocoder.
