The Edge

In this video of U2 performing "Ordinary Love" acoustic on 'The Tonight Show starring Jimmy Fallon,' The Edge can be seen playing a Taylor 818e Acoustic-Electric Guitar. This can be confirmed by a comment that Taylor Guitars made on the YouTube video Feb 24, 2014. They commented, "Here again is the performance of "Ordinary Love" with U2's Edge using a Taylor 818e #guitar. This has been making the rounds at Taylor HQ, glad to see it made available"

There is, however, a marking on the headstock that a stock 818e doesn't appear to have - perhaps something custom for Edge.

In this video, Edge demonstrates various guitars of his, both vintage and current. At 4:03 into the video, he picks up his Line 6 Variax 700 Acoustic (with what appears to be a custom finish). He says, "What's good about this one is that you can change the tuning by just... [he goes on to demonstrate the controls of the guitar] I ended up playing The Fly on this guitar, and the guy who designed it was watching me play and was like 'Oh my god, we didn't design it for that kind of abuse!' But it works really great."

In this Rig Rundown feature for Premier Guitar magazine, longtime U2 guitar tech Dallas Schoo shows off Edge's 2018 touring rig, which includes an EF341SC that was gifted to him by Bruce Springsteen.

At :58s of the "Christmas, Baby Please Come Home" music video, you can see The Edge playing a Yamaha AE2000.

Visible in this photo, The Edge used this model at Woodstock 1981.

Here Edge can be seen playing a Kingman acoustic at a recent concert in Paris.
