FX747 Supersonic Stereo Flanger
The DOD FX747 Supersonic Stereo Flanger is a versatile analog modulation pedal produced between 1996 and 1998 as part of the celebrated Lamb series. Known for its lush, sweeping textures, it features a true stereo output that creates expansive, immersive soundscapes. The pedal is unique for its aviation-themed control labels: Payload (Level), Mach (Speed), Altitude (Width), and Thrust (Regeneration). A standout technical achievement is the Mach control's extended range, which allows for exceptionally slow flange speeds, enabling musicians to play into the effect rather than just with it. Its all-analog circuit, built around high-quality bucket-brigade device (BBD) technology, delivers a broad tonal palette ranging from subtle, tasteful overtones to aggressive, metallic "jet-engine" swooshes. Housed in a durable silver-finished metal chassis with a wide footswitch, the FX747 is highly regarded by collectors as an underrated classic that offers professional stereo modulation at an accessible price point.
