At 5:11 in this video, when talking about his pedals, Jason Newsted mentions his "original flanger," bought "way back in the day," which he describes as just a "regular old purple flanger."

As seen in this Guitar Geek rig diagram, Coxon used a Boss BF-2 in 1993.

In this pic there is clearly a Boss BF2 visible

In this screenshot of the Tibetan Freedom Concert in 1996, we can see the pedalboard of Pat, it is composed of a ProCo Rat 2 (see one of my previous submission), a Arion Stage Tuner (we can clearly see that it’s the Arion Stage Tuner), a Boss BF-2 (sure it’s the Boss BF-2 because of the shape and color of the pedal but also of the live at Concert Hall 1996, where during the noise part of Exhausted we can ear a Flange effect, and the version is the Japanese one with the black knobs), and a Digitech Whammy II (sure it’s a Whammy II because of the shape, footswitch, and color of the pedal).

In the video "The Mars Volta - At The Drive In - Omar Rodriguez Lopez - Gear Rundown - Guitars, Amps, Pedals" by Future Sound Music on YouTube, Omar Rodríguez-López is shown using the Boss BF-2 Flanger around the 3:01 mark.

Ray Toro most notably used the Boss BF-2 Flanger in the Intro and Verse parts for "The Ghost of You". Ray Toro can be seen using this pedal live on the "The Ghost of You" AOL Sessions video as well. Additonally, the BF-2 can also be heard in songs throughout the album Three Cheers for Sweet Revenge -- such as the chorus/verse link in "Helena", the intro verse in "The Jetset Life Is Gonna Kill You", before the second chorus of "It's Not a Fashion Statement, It's a Deathwish", and the pre-chorus & clean bridge of "I Never Told You What I Do for a Living".

The BF-2 can also be heard on a recorded live cover of Morrisey's "Jack the Ripper" -- which is featured on the My Chemical Romance EP, Like Phantoms Forever.

El Boss BF-2 formó parte del set de Gustavo en Soda durante 1986 - 1987. No era un efecto que utilizaba muy seguido en los shows, pero sí se puede distinguirlo en "Afrodisiacos", más específicamente en la introducción que solían hacer en esos años. (escuchar la versión del show en Obras 1986)

In a Guitar Center Music session hosted by Vox Amps on YouTube, Brendon Urie is seen using the Boss BF-2 Flanger in his setup.

According to this site he uses analog flanger by Boss.

In this interview from the October 2004 issue of Bass Player magazine, Simon says that he uses the BF-2 in his live rig.

Pictured on Gallagher's official website's "Effects / Pedals" page and mentioned in an interview in an August 1991 Guitar for the Practicing Musician 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.

Another pedal in the Boss range. The BF-2 Flanger. This purple pedal is in my view the best flanger available. It was a veteran pedal in Squire's set up and served him well in the sound quality department. This pedal is commonly known for being able to emulate a jet engine type of sound.

Squire would use this pedal mostly for intense sweeping sounds over chords during various sections of tunes live.E.g End of She bangs the drums, "You're eyes are gazing back from...." middle 8 bit in Sally Cinnamon, Made of Stone chorus, spacey sounds during the instrumental of Resurrection etc.If set up for the jet engine sound, the pedal can really give a sound like you are about to take off at 1000mph!! It's certainly great fun to strum through a chord and hear the this effect full on. It can also be set up for more subtle chorus type sounds and wierd wobbly sounds, although Squire seemed to opt mainly for the sweeping swooshy sounds.

These pedals have risen in price quite recently and are probably about £80-£90 brand new. It may sound quite a lot but boss pedals are fantastic quality and well worth the money. It is a very versatile pedal and is certainly worth putting in the time to experiment with it. This will make the money spent a bit more justifiable. Personally, I feel the jet sound alone is worth the money!!! Again, from the Tokyo picture it may seem impossible to tell it's a flanger but it's the only boss pedal that has an extra trim around the control panel which can be seen from the pic if you get eagle-eyed. This pedal can also be seen from the blackpool pic at the end of Squire's pedal chain.
