Larry Mullen, Jr.

According to the website U2: Stage And Studio, Larry Mullen, Jr. used a "Yamaha 10" Peter Erskine model snare drum" during U2's 360° Tour

According to the website U2: Stage And Studio, Larry Mullen, Jr. used a "14" Ludwig (hammered) Black Beauty snare drum" during U2's 360° Tour.

You can see this snare on 4:00. This drum was used during the October tour and perhaps before.

Larry Mullen, Jr can be seen using the Yamaha SD-493 14x3.5 Brass Piccolo Snare Drum on both the Joshua Tree Tour (1987) and the Lovetown Tour (1989-1990). He used it as a main snare rather than an auxiliary snare. It gets several features on many of the performances during the "Rattle And Hum" movie, notably on "With Or Without You". During 1:37 and 2:42, you get a shot of Larry playing the kit and the snare is able to be seen in use. During every concert on these tours he used this snare, so if you have footage of these concerts you'll be able to see the snare, depending on the angle and camera shot. I believe he used this snare on the recording of "The Joshua Tree" album as well, based on the similarities of the snare sound on the record and live. On "U2: Rattle And Hum, The Offical Book Of The U2 Movie", at the back it mentions the gear each of the band members used which includes the Yamaha SD-493.
