The Original Chorus in Pedal Form Chorus lovers, rejoice — the original chorus effect is now available in pedal format! The Behringer Chorus Symphony chorus and vibrato pedal is a re-creation — not an emulation — of a famous solid-state amp’s lush chorus effect. Enclosed in a durable metal enclosure with retro styling lies the quintessential preamp circuit and warbly sounds you and other tone chasers have come to know and love. Switch the Chorus Symphony to Vibrato mode to unlock those classic spacey sounds that were once only achievable from the mammoth-size amp that has been used by countless artists, including Joe Satriani, Andy Summers, John Frusciante, and many more. Use the Chorus Symphony in stereo with two amps to further expand your tone to even wider lengths.
