Kauer Guitars is a boutique electric guitar and bass builder founded in 2008 by Doug Kauer in Elk Grove, California, near Sacramento. Raised in a family of woodworkers, Kauer parlayed a background in his father's cabinetry shop into a small luthier operation that produces instruments in-house with a team of builders. The company is known for combining traditional construction techniques with distinctive, often offset body designs.

The lineup spans neck-through, set-neck, and bolt-on models, including the Banshee (Standard and Deluxe), the Gripen, the Starliner (offered in JR, Express, Deluxe, and Thinline variants), the Super Chief, the Korona Supreme, the Electroliner, and the Draken bass. The Banshee is notable for its reverse-offset silhouette, while the Starliner is a slab-bodied Spanish cedar guitar built in the spirit of classic set-neck singlecuts.

Kauer instruments have been played by Scott Holiday of Rival Sons, Brad Whitford of Aerosmith, Tom Dumont of No Doubt, Dennis Casey of Flogging Molly, Josh Ramsay of Marianas Trench, and Will Swan of Dance Gavin Dance. The brand has developed a reputation in the boutique guitar community for handcrafted small-batch production, playful marketing, and a willingness to blend vintage-inspired voicing with modern ergonomics.

Kauer Guitars has 17 products cataloged on Equipboard, including Solid Body Electric Guitars, Semi-Hollowbody Electric Guitars, and Electric Basses. Their gear is featured by 13 artists, with the strongest followings in Rock, Pop, and Metal. Notable users include Scott Holiday, Joe Hottinger, and Will Swan.
