[*Music Radar*](http://www.musicradar.com/news/guitars/u2-exclusive-the-edges-stage-setup-revealed-223342/) talked with The Edge's guitar tech, Dallas Schoo about this pedal, to which Dallas replied "Oh, they're great! We're using the Supersonic Fuzz Gun and the [Harmonic Transformer](http://equipboard.com/items/death-by-audio-harmonic-transformer-pedal). This guy, Ben Curtis - great guy - he makes these different distortion pedals and he turned us on to them...The Fuzz Gun is on No Line On The Horizon, that big intro sound. It's on Ultra-Violet, too - it's fantastic. The guy is always looking for something new that can create music, and he'll tinker with a pedal or a device for days until he can make it do something he wants."more
This website contains an excerpt from an [interview](http://u2-stage-and-studio.com/edge/id83.html) with [U2's](http://equipboard.com/band/u2) [the Edge](http://equipboard.com/pros/the-edge), who credits Ben with having introduced him to this pedal. "I used Death By Audio's Supersonic Fuzz Gun on the song 'No Line on the Horizon,' and a couple of others I think. It was Ben Curtis who turned me onto them. He's one of the Curtis Brothers from Secret Machines -- he's got a new band now called School of Seven Bells, who are pretty interesting."more
Try before you buy, cause this monster isn't for everyone. It will drone, buzz, fizz, fuzz and velcro. Pricey, but unique. Most people go SSFG or Fuzz Factory (if you want crazy fuzz).
Got one of these because I heard Edge from U2 uses one... I know you should never just model your pedal setup after your heroes. I like the pedal a lot, it's... neat. It's supposed to be an experimental fuzz but I think of it more as just a plain old boutique distortion. I actually think it's more useful for synths and drum machines. The fuzz on this thing has a weird, robotic squelch after a note is played (which is on purpose). Has pretty limited use.
