This preamp/effects combo packages vocal and guitar processing with real-time harmonies and looping in a single convenient package. You have instant access to the premium vocal processing you’ve come to expect from other BOSS vocal units, with features designed to polish your vocal performance. You also get pitch correction to help you stay on pitch and the harmony section tracks your chords and key to provide excellent backing harmonies on the fly. For your guitar, the Acoustic Resonance combats the “quack” inherent with some piezo pickups, while also putting popular effects at your fingertips.
