A Smart, Funny, and Heartfelt Celebration of the World’s Most Beloved Instrument

What do executives from iconic American guitar brands Fender, Gibson, Taylor, D’Angelico, and Martin Guitars’ legendary builder Dick Boak have in common with former FBI Deputy Director Andrew McCabe and former Assistant Attorney General Harry Litman?

And what do four of the world’s most influential online guitar teachers—Marty Schwartz (USA), Justin Sandercoe (UK), Tyler Larson (USA), and Charlie Wallace (New Zealand)—share with distinguished academics, a neuroscientist, a CNN medical analyst, and owners of some of the most iconic guitar shops in the U.S. and U.K.?

The answer is String Theory: Guitar Obsessed, a feature-length documentary that explores the passion, psychology, culture, and obsession behind the guitar—told by legends, innovators, and some truly unexpected voices.

Directed by 2x Emmy Award–winning filmmaker Jarett Bellucci and created alongside comedian and writer Randy Levin, String Theory: Guitar Obsessed takes a humorous yet reverent look at why the guitar continues to shape lives across generations, professions, and continents.

FROM PASSION PROJECT TO FEATURE FILM

Bellucci and Levin first met in the spring of 2022 while working on a television commercial. Bonding immediately over their shared love of guitar, Levin soon pitched Bellucci the idea for a small documentary. Initially envisioned as a 10–15 minute YouTube video, the project quickly grew beyond expectations.

Within just nine weeks, and with no prior documentary experience or industry contacts, Levin successfully reached and scheduled interviews with 20 high-profile figures, each eager to share their relationship with the guitar. Bellucci—who has spent 25 years in the industry—recognized something rare unfolding.

In total, 24 distinguished voices ultimately joined the film, transforming String Theory: Guitar Obsessed into a full-length documentary driven entirely by genuine passion for the instrument.
