Siggi Braun - Fine Young Guitars is a custom electric guitar builder based in Göppingen, Germany. Founded by luthier Siggi Braun, who began developing his own designs and neck-body joint system in 1990 and formally established the workshop in 1993, the company handcrafts instruments on commission alongside offering a repair service. The shop's output spans several product lines, including Vintage-style models (Relic S-Type, T-Type, Spirit of '59, Sparrow), Modern designs (Little Crow, Indian Summer, Angel Wing, Boo, Raven, Icarus), multiscale/fan-fret models (Fafnyr, Griffin), and a Preci-Bass.

The brand is known for its signature models built in collaboration with artists, including a line for Rage guitarist Victor Smolski (who has been associated with the workshop since 1996), Greek guitarist Gus Drax, and a model called The Serpent developed with Joseph Salvatori. Siggi Braun also designs Zenrok Guitars, a related line manufactured in Korea to his specifications, offering versions of his designs at a more accessible price point.
