Roland - AP-7 Jet Phaser

"... Most people know Roland Corporation for one of two reasons: One; for its amazing synthesizers and drum machines spanning several decades. Two; as the parent company of Boss, the biggest effects brand on the planet. Some pedal enthusiasts are unaware that Roland itself made pedals—good ones! 

For a time in the ‘70s, Boss and Roland intermingled with one another, with Roland choosing to slap the Boss name on certain effects (CE-1, DM-1, DB-5) and its own name on the rest, even though some of this gear shared similar enclosures, and even though some pedals were branded as one company, but as the evolution of the other company’s innovations (such as the Boss CE-1 being a standalone Roland Jazz Chorus effect). I’m here to talk about perhaps the most unsung vintage Roland piece; the AP-7 Jet Phaser.

For reasons unbeknownst, Roland excelled at ensconcing a stellar (oftentimes dirt) circuit within the confines of another, larger pedal and releasing the non-dirt part as a standalone model. One such example is the AD-50 Double Beat fuzz wah, containing an absolutely disgusting fuzz circuit yet releasing the AW-10 Wah Beat. 

The Jet Phaser is just such a circuit, combining phaser with, well . . . “Jet.” Much like the fuzz section from the Double Beat is—by virtue of naming conventions—a form of “beat,” “Jet” refers to an absolutely screaming distortion effect that sits in front of a juicy phaser circuit—the same one found within the AP-2 Phaser. 

This highly-adapable Jet circuit transforms the mild mannered phaser into a pulverizing throb, jumping out of the mix with some serious propulsion. Larry Graham of Sly and the Family Stone famously used one, as did Ernie Isley of the famous brothers, on “Who’s That Lady?.” In fact, that thick, viscous fuzz you hear on that cut’s leads is the characteristic Jet sound, and has been one of the most quietly sought-after lead tones in history. 

The Jet side of the circuit has no analog in today’s pedal market, it’s a curious piece of circuit, featuring equal parts discrete semiconductors and monolithic op-amps. A rotary switch on the face of the unit selects between four forms of Jet and two of Phase. Switching between the Jet settings yields different tonal compounds, cycling between gain stages, a notch filter and more. All of this is controlled by one master Jet knob, which offers varying intensity rather than a simple volume. On all Jet settings, the phaser is integrated; no configuration offers an isolated Jet section.

On the phaser side, we have an eight-stage FET-based phaser with a Resonance control. As far as vintage offerings are concerned, eight stages—the MXR phaser line of the 45, 90 and 100 offers two, four and six stages respectively—is quite a feat. With the added Resonance control, the phaser section can actually give your amp a little bit of a nudge at the peaks.

Much like the Maestro PS-1A (and B), the Jet Phaser offers a Fast/Slow footswitch that comes in the form of . . . an actual footswitch instead of clunky organ rockers. Maestro’s model offers ramping between speeds if you switch it on the fly; difficult if you’re not wearing pointy heels or cowboy boots, so the ramping feature wasn’t a tactfully expressive performance tool. The Jet Phaser solves all this by offering a Fast/Slow switch and letting you set your slow speed with a knob (the “Fast” setting is just this same knob turned all the way up). When switching between the two speeds, the rate gradually descends to the desired level.

Finally, I would be remiss if I didn’t include my all-time favorite effects-adjacent video—Larry Graham absolutely shredding on a Jet Phaser. ..."

Royal - RE-202 Jet Phaser

"The Beast From The East. 1977 RE-202 Jet Phaser. Branded “Royal”, but identical to the more often seen Aria RE-202. Cast metal box, 18v, huge footprint - like four regular Boss pedals together. Big pedals sound better. There appear to have been two Aria versions - the other being without the fuzz volume seen here. Like all fuzz/phase combos, this is great fun on guitar - Hawkwind-style wigouts are irresistible. However, I suspect this is most interesting with a bass - Larry Graham used an Roland AP7 Jet Phaser to great effect and this is definitely a knockoff of that. The Roland and its clones also have a significant volume drop when the fuzz comes in, so these are either “on” all the time (unlikely, except when recording a specific part) or belong in a loop with a boost. The options are bypass/phase only/phase with “jet” fuzz, but no fuzz by itself. Realistically this is a special occasions in-your-face brain melt effect and deserves to be kicked on in full force, with both effects on, when an audience least expects it."

Hey, friends! Other Mike wanted to ask if any of our followers had a line on an old Roland Jet Phaser. He's been wanting one for ages (another "should have never sold it" situation) and I want to get him one!

If you or any of your friends have one for sale, hit us up!
