Roland Jet Phaser AP-7

The Roland Jet Phaser AP-7, introduced in 1975, is a legendary effects pedal that combines a high-gain fuzz circuit with an eight-stage phaser, creating a unique and powerful sound. Designed during the golden age of pedal innovation, the Jet Phaser stood out for its ability to produce both traditional phasing effects and aggressive, jet-like tones when the fuzz ("Jet") mode was engaged. Its six modes offered two phaser-only settings and four fuzz-phaser combinations, with controls for Jet Level (fuzz intensity), Resonance, and Slow Rate. The pedal's robust build and distinctive sound made it a favorite among bassists and guitarists seeking bold, experimental tones. Though discontinued in 1978, the Jet Phaser remains highly collectible and influential, inspiring modern recreations.

Historical Development

• Release (1975): The AP-7 was part of Roland's early foray into effects pedals, combining their expertise in modulation circuits with a unique fuzz design.
• Design: The eight-stage FET-driven phaser provided a deep, swirling effect, while the fuzz circuit added aggressive distortion. The Fast/Slow footswitch allowed dynamic speed changes, making it versatile for live performances.
• Legacy: Despite its short production run (1975–1978), the Jet Phaser became iconic for its innovative design and distinctive sound.

Notable Players

• Larry Graham (Sly and the Family Stone/Graham Central Station): Famously used the Jet Phaser to craft his signature growling bass tone on tracks like "Pow."
• Herbie Hancock: Incorporated it into his electric piano rig during his jazz-fusion era.
• Isley Brothers: Used it to create textured guitar tones in their funk recordings.

Popular Settings

The Jet Phaser's flexible controls allow for diverse applications:

• Classic Phaser: Use one of the two phaser-only modes with Resonance at noon for smooth, traditional phase-shifting effects.
• Jet Mode: Engage any of the four fuzz-phaser modes with Jet Level high for aggressive, jet-engine-like sweeps.
• Funky Bass Growl: Combine a moderate Jet Level with slow phasing for Larry Graham-style bass tones.

Legacy

The Roland Jet Phaser AP-7 is celebrated as one of the most innovative pedals of its time, blending fuzz and phasing into a single unit that pushed sonic boundaries. Its association with artists like Larry Graham and Herbie Hancock highlights its versatility across genres like funk, rock, and jazz fusion. Although vintage units are rare and highly sought after, modern recreations by companies like Warm Audio ensure its unique sound continues to inspire musicians today.
