Bourgeois Legacy Series Banjo Killer SDThe name Banjo Killer was coined by Bryan Sutton for his six stringed onstage sidekick, back in the day when he burst onto the bluegrass scene in the late 1990s. Featuring a double scalloped X brace design, stiffer back bracing and a 25. 5 scale, the Banjo Killers bark is as terrifying as its bite. AT Adi Spruce, figured Mahogany and our distinctive snakehead headstock round out an otherwise understated aesthetic presentation.
