Warm Audio Jet Phaser
Warm Audio · pedal
The Warm Audio Jet Phaser is a recreation of the 1970s Roland AP-7 Jet Phaser, a combined phaser and fuzz circuit. It pairs deep, swirling phase modulation with a hot, searing fuzz, and offers four modes: the second intensifies the swirl and, with resonance raised, gives the searing jet-engine character the original is named for, while modes three and four are mellower, rolling off the upper frequencies so the phaser and fuzz blend into a swirling snarl. At low resonance the phase voice adds subtle animation and shimmer; at high resonance it takes on a rotary-speaker wobble. A Jet control doubles as a solo boost, and holding the Fast/Slow footswitch lets the modulation settle at in-between speeds like a real Leslie.

“The Jet Phaser is sought after by players wanting the distinctive Roland AP-7 tone — a combination of phaser sweep and fuzz circuit interplay that creates textures”
— from the community notes
“The fuzz-plus-phase combination is the whole point and it is genuinely distinctive: searing and aggressive in mode two with resonance up, mellower and more blended in modes three and four”
— from the reviews
“The trade-offs are authenticity-driven: it is a large enclosure, runs on 18V or two PP3 batteries, and keeps the original's layout”

Trade-offs
“In the signal chain it typically sits after volume and before reverb”
