Vintage '70s modulation pedal with BBD chorus and vibrato modes, variable input range, and wide 3D stereo effect. This authentic ’70s modulation pedal features chorus and vibrato modes, based on classic Jazz Chorus amplifier BBD circuitry. It includes a legendary preamp with a variable input range for use with different instruments, dual outputs for a huge 3D stereo spread, and a simple one-knob control that adjusts both speed and depth of the chorus. The vibrato mode has independent depth and rate controls. It is designed with all analog circuitry and authentic BBD chips, an internal slide switch for optional buffered or true bypass, and a robust housing with authentic vintage styling.
