Kerrang No. 15, May 6-19 1982

"I use the Boss FET pedal which, although a transistor, has been designed to sound as much like a valve as possible. It still can't beat the old Dallas Rangemaster that was doing the rounds in the 'sixties though. The company's now gone bust so they're like gold dust if you can find one. I have a couple but they've corroded with use. They used to be lethal. They'd not only boost the bass and treble, but give you a couple of extra watts as well!

Guitar for the Practicing Musician, August 1991 interview with Vivian Campbell

VIVIAN: You get a tremendous tone for a single-coil Strat. Are you using any kind of distortion device between the guitar and the amp?

RORY: I've got a Boss Graphic EQ.

VIVIAN: Is that a little 6 band?

RORY: Yeah, one of the real old green ones. And I've got a DOD analog. They're back on the amps, and that's set at the minimum setting, just for a little bit of slap-back. I've got a Dyna-comp, which is on all the time, to drive the songs from the leads. It's not for effect. It's a form of compression and I have it at a setting where the compression's really low on it. I usually use a Tube Screamer, which broke down on me. Last night I was using a Boss overdrive. I use them for some solos, not all solos. I was against using them for years. If I was doing a solo, I had to look at the monitor guy to turn it up and all this. So I keep close to the natural sound. I have a brown Boss octave thing.

VIVIAN: I heard that last night. You sounded like Prince! He uses that a lot.

RORY: I've got a Boss flanger, as opposed to a chorus, which I use sparingly, I use that only in “Shadow Play” and “Moon Child,” and one other song. That's my talk on technology. I have a Vox wah-wah which I did use for one or two gigs, but purely to click it on for slide solos. I used it in the studio, for some solos as well. I don't use it on-stage, because even as it is, I try to keep it simple, within reason.

At 22:17 in this Rig Rundown for Tommy Henriksen of Warlock, Mojo Gurus, Clear Static, Benedictum, Cavo, Emphatic, China, Hyper Crush, and Revis, his gear is displayed, showing his Boss FA-1 Amplifier Pedal.

In a Facebook post by Yuzo Kosakai, it is explained that Fumio Kosakai used the Boss FA-1 FET Amplifier during the early days of Incapacitants.
