Bizarre guitar choice to play a very clean acoustic sound Paul Simon is playing a Parker Fly guitar when guesting at a gig with Bob Dylan.

During his late career, Simon uses the cherry red Epiphone Riviera, the 12-string version. Although it looks new, this Epiphone article says that this is a vintage Riviera. He also performed "So Beautiful or So What" on this guitar during the Saturday Night Live performance.

Paul used this guitar during the 1980, most notable for The Tower Theater concert, where he can be seen with it at around 3:11 minute mark.

Through the entire appearance with Sting on February 16, 2014 Paul can be seen using his Fender Classic Esquire Telecaster in Butterscotch with a rosewood neck.

From ACOUSTIC GUITAR [July / August 1993] No. 19, "Gearbox", p. 94:

"His favorite acouistic guitar is a Gurian. 'In a way, this should be the guitar that I build the microphones in and bring out to play on the stage," he says. But this is the guitar that I record with, so I don't want to fool with it because I don't want to take a chance that I'll alter the sound."

From FRETBOARD JOURNAL [May 2011] - "Paul Simon Stays Cool" by Jason Verlinde:

"A month or so ago, Paul Simon played an extra show while stopping through Seattle. He could have packed another full-sized arena but, after playing at the cavernous, arena-esque WaMu Theater, he did a show at the much smaller Showbox at the Market. This is the kind of venue he hasn’t played for years… a place that only holds a few thousand folks and has amazing sightlines no matter where you stand. And he seemed to have a great time playing this club; it almost felt like a thank you gift to his fans for supporting him over the years.'

"Then, a couple of weeks back, there was a nice Rolling Stone feature on Simon and his new album. As a guitar geek, the most impressive thing for me was the guitar of choice in the opening photograph of the article: it’s Simon holding his old Size 3 Gurian. Sure, Simon has a signature model Martin but the axe he grabbed when the photographer from RS came by was his “old friend,” the Gurian. What a cool gesture."

Paul Simon is associated with a Sadowsky Custom Guitar, styled like a white Strat, as detailed on Biglobe's "Paul Simon's Gear" page.
