A/DA Flanger

The A/DA Flanger, introduced in January 1978 by Analog/Digital Associates (A/DA), is a groundbreaking flanger pedal that set a new standard for modulation effects. Designed by Dave Tarnowski, it was one of the most advanced flangers of its time, featuring the Reticon SAD1024A Bucket Brigade Device for rich, analog warmth and a wide range of tonal possibilities. Unlike its contemporaries, such as the MXR Flanger and Electro-Harmonix Electric Mistress, the A/DA Flanger offered unique features like a Threshold noise gate, an Even/Odd Harmonics switch, and compatibility with external control voltage pedals for manual delay sweeps. Capable of producing everything from subtle modulation to dramatic jet-plane sweeps and experimental sounds, it remains a favorite among musicians.

Historical Development

• Origins: The A/DA Flanger was inspired by studio tape flanging techniques but adapted into a pedal format with unprecedented flexibility. It quickly became a favorite for its ability to emulate tape flanging and produce unique effects.
• Revisions: In mid-1978, the Reticon SAD1024A chip was replaced with the Panasonic MN3010, slightly altering its sound. Production ceased in 1981, but reissues in the mid-1990s and modern recreations have kept its legacy alive.
• Legacy: The A/DA Flanger is celebrated for its versatility and remains sought after by collectors and players. Modern versions and clones continue to honor its innovative design.

Notable Players

• Adrian Belew (King Crimson): Used the A/DA Flanger extensively for unorthodox textures and animal-like sounds on King Crimson records.
• Paul Gilbert (Racer X, Mr. Big): A long-time user whose love for the pedal inspired his Ibanez Airplane Flanger.
• Omar Rodríguez-López (The Mars Volta): Incorporated it into his experimental rig for psychedelic soundscapes.
• Pat Travers: Used it to add depth and richness to his guitar tones.

Popular Settings

The A/DA Flanger's controls allow for a variety of creative applications:

• Classic Jet Sweep: Manual at noon, Range at max, Speed at 9:00, Enhance at 3:00 for dramatic flanging sweeps.
• Chorus-Like Modulation: Manual at 10:00, Range at noon, Speed at 12:00, Enhance at 9:00 for subtle movement.
• Experimental Sounds: Manual maxed out with Even Harmonics engaged and Threshold adjusted for gated effects or pitch-bending textures.

Legacy

The A/DA Flanger remains one of the most revered modulation pedals in music history. Its combination of analog warmth, advanced controls, and versatility has made it indispensable for guitarists seeking both classic and experimental tones. With its influence spanning decades and genres—from rock to experimental music—it continues to inspire musicians worldwide through vintage units and modern reissues.
