Bono

Bono's signature guitar is the Gretsch Irish Falcon.

In this video, Bono can be seen playing a Black Fender Lead II in a live performance with U2 at Red Rocks.

According to Gretsch's blog, Bono is quoted as saying, "“The (GRETSCH)RED guitar is a guitarist’s dream. And the reality is that every time someone buys one, it’s raising money to fight AIDS. That money can buy life-saving medicine for pregnant mothers living with HIV, and prevent their babies being born with the virus. They’re the same pills that will help deliver an AIDS Free Generation.”

Paul Waller, a Master Builder in the Fender Custom Shop in Corona, California built this telecaster for Bono in 2011. In this photo, Bono can be seen playing the guitar during a live U2 performance (the pickguard appears to have been removed from the guitar). The guitar has a semi-hollow Fender Telecaster style body with f-holes, and the pickups look to be TV Jones Filter’Tron style pickups (possibly TV Classics). The guitar also features Gretsch style gold binding and Gretsch style knobs.

Some of the information is according to a forum post made by a user who says he's Paul Weller's father-in-law.

Here, Bono is shown with his custom black Gibson ES-175. In this photo the words "I Feel Good" have been added to the bottom of the guitar.

In this photograph, we can see Bono playing his Elvis Presley Dove live onstage. He has been seen with the guitar many times over the years, starting primarily around 1991's Zoo TV Tour.

In this video, at 3:05, Bono can be seen playing a Gibson Hummingbird in a wine red finish.

Bono used a Gibson ES-335 from 1987-1990, during the Joshua Tree &Rattle and Hum tours.

Bono can be seen in this photo playing a Gibson J-200.

In this top of the pops performance of "New years day" in 1983, Bono is seen with a Fendere telecaster deluxe in black.

In this photo from the Zooropa sessions, you can see Bono playing a Gibson Les Paul Custom. (Photo from Vox Magazine, August 1993 page 21, according to website U2 Bono Files.)

This guitar was used by Bono during the Popmart tour for "Gone," as seen in this clip here.

Bono has used a Vox AC30 combo for most of his career.

Here is a picture of Bono's handwired AC30 that was used for the U2 360 tour.

The transcribed article accompanying an equipment list from U2 MAGAZINE No: 1 in November 1981 states that "Bono also has a guitar - a black Fender Lead 2. This is fed through a Roland Bolt 60 combo miked with another Sennheiser MD421."

We can actually catch a glimpse of the Bolt-60 onstage in this live video of U2's performance at the Werchter Festival in 1982. At the 26 second mark, if paused, the amp sits in the background to the left of the Edge's elbow.

From the Sound On Sound March 1994 article "Robbie Adams: Recording U2's Achtung Baby & Zooropa":

Bono's vocals were largely recorded with an SM58 and compressed with a Summit compressor. Adams: "Instead of using the Summit, what we did on several of the tracks on Achtung Baby was to record his vocals on tape with Dolby SR and play it back without Dolby SR. It tightens up the vocal sound and gives it more brightness and presence. It makes his voice sit really nicely in the mix and easier to balance."

In one scene, Bono can be seen using a Fender Precision bass in this mini-documentary

Bono can be seen in this photo playing a Yamaha CP 80.

Bono is nearly unrecognizable without his trademark sunglasses. However, the U2 front-man's distinct look is more a product of necessity than styling. He explained the shades to Rolling Stone and told them he uses the glasses to protect his blue eyes. "[I have] very sensitive eyes to light. If somebody takes my photograph, I will see the flash for the rest of the day," he said.
