Since helping launch the
first UAFX pedals, we’ve continued our creative partnership with Universal Audio across a growing line of amp-in-a-box offerings. Their latest release—
Knuckles '92 Rev F—channels the raw power of the original Mesa Boogie Dual Rectifier, a high-gain icon synonymous with late ’90s and early 2000s heavy music. Built for players chasing that aggressive, mid-scooped bite, Knuckles ’92 distills the chaos of a full-stack monster into a compact, tour-ready pedal.
To bring this story to life, we embedded with
Bill Kelliher and
Brann Dailor of
Mastodon during a live recording session at the band’s West End Sound studio in Atlanta. Shot in a documentary style, the film celebrates the creative process with handheld camera work, textured film grain, and urban b-roll woven between moments of candid performance.
Working with longtime collaborator and cinematographer
Brett Carlson, we produced and directed this visceral look at tone under pressure—raw, loud, and undeniably real.
