The Tone City Silver Angel Chorus Vibe Pedal is an all analog circuit based on a famous BBD chip Chorus Vibe pedal. The prototype of this pedal is one model that J. Wong made 14 years ago, the core components are stopped produced many years ago. But it is lucky we find enough 100% new and original stock, so it is redesigned and emerge in this series. It has an extremely lush and natural tone. In addition, we have added vibe mode, so you can get an extra classic vibrato sound!
