The Multivox Big Jam SE-11 Jazz Flanger is a very rare and highly collectible vintage modulation pedal, made in Japan and known for its lush, analog flanging tones. Equipped with the coveted Reticon SAD512 Bucket Brigade Device (BBD) chip, the SE-11 delivers a smooth, swirling effect with rich harmonic movement and a warm, organic character that digital units simply can’t replicate.
Produced in the late 1970s to early 1980s, the SE-11 is part of the iconic Big Jam series from Multivox, a brand revered for its innovative, boutique-style pedals during the golden age of Japanese effects manufacturing. The "Jazz Flanger" name is no gimmick—the SE-11 is especially responsive to clean tones and chordal playing, making it a favorite for jazz, fusion, and ambient textures, though it also excels with distorted tones for experimental and psychedelic styles.
The controls are straightforward and musical, offering adjustment over Speed, Width, and Manual parameters. These allow precise shaping of the flange sweep, from slow, tape-like modulation to fast, jet-engine whooshes. Thanks to the BBD circuitry, the SE-11 produces a thick, three-dimensional effect with a warm delay tail that feels alive and dynamic.
This unit, serial number 00761, is fully functional, tested, and in excellent working condition for its age. A true gem for collectors, tone chasers, and fans of vintage Japanese electronics. Add some swirling analog magic to your setup with the Multivox SE-11 Jazz Flanger.
