Stevens Custom Guitars is a luthier brand based in Munich, Germany, founded in 1992 by Stefan Zirnbauer and Werner Kozlik as the custom-build arm of the Munich Guitar Company. Zirnbauer trained as a guitar maker in the mid-1980s and earned a national gold medal for a steel-string cutaway masterpiece, and the workshop has since grown into one of the larger master luthier shops in Europe. Kozlik leads the acoustic instrument-making side, while Zirnbauer handles the repair workshop and custom electric construction.

The shop is best known for its handmade steel-string acoustics — including OM-style models such as the Stevens OM Stage and small-body designs like the Stevens O-BW 12-fret — alongside Irish bouzoukis, a range that brought the workshop wider recognition in European folk circles. The product line also covers classical and concert guitars, jazz archtops, electric guitars and basses, acoustic bass guitars, ukuleles, mandolins and mandolas, with an in-house lacquering facility used across the catalog.

Beyond standard models, the workshop accepts fully bespoke commissions, working to individual specifications for tonewoods, scale length, neck profile, and aesthetic detailing. Stevens has exhibited at boutique builder events including the Holy Grail Guitar Show, where its acoustic and folk instruments are typically the centerpiece of the booth.
