OJ Guitars, founded by Swiss luthier Oliver Jaggi, represents a fearless blend of engineering precision, tonal exploration, and artistic vision. Rooted in three generations of Swiss craftsmanship and shaped by the landscapes of the Alps and Rockies, Oliver’s instruments push boundaries while honoring tradition.

His most iconic creation, the BrummBass, stunned audiences at the 2019 Winter NAMM Show, where it earned a Best of Show Award from Bass Gear Magazine. With its commanding presence, detachable neck, and piano-inspired tonal depth, the BrummBass is more than an instrument—it’s a bold artistic statement.

“The BrummBass is obviously a labor of love, and believe me, if you play it, you will love it.” — Kevin Johnson, Bass Gear Magazine

“This bass was such an original piece of work that it stopped me cold in my tracks… Art for art’s sake.” — Phil Maneri, NAMM Review

Every OJ Guitar reflects Oliver’s uncompromising approach: meticulous design, original engineering, and an enduring dedication to creating instruments that are both functional and visionary.
