The A/DA Flanger is an iconic analog flanger pedal that first hit the market in the late 1970s, created by Analog/Digital Associates. It quickly set the standard for flanging effects, thanks to its lush, expansive modulation sounds and sophisticated circuitry. This pedal can deliver a wide range of tones, from gentle, rich flanging and chorus-like effects to intense jet-swoosh sweeps and metallic sounds. It features controls for Manual delay adjustment, Range (depth), Speed (rate), Enhance (feedback intensity), and the selection of even/odd harmonics, enabling extensive sonic customization beyond standard flanger options. With its sturdy cast metal construction and unique tone, it has become a beloved classic among guitarists and collectors.
