Rauen Guitars stands as one of Milwaukee’s premier destinations for guitar repair and restoration, led by master luthier Denny Rauen. With over 40 years of experience in building, restoring, and modifying string instruments, Denny has earned recognition as one of the nation’s finest luthiers, featured in Guitar Player Magazine in 1988.

The shop specializes in vintage guitar work and custom boutique guitar builds, bringing world-class expertise to every project. Denny’s credentials include inventing the compound radius fretboard in 1978‚a revolutionary innovation that enhanced string bending mobility and was later adopted throughout the luthier community. His expertise even caught the attention of Leo Fender himself, with whom Denny discussed his multi-radius innovation in 1981.

From complex restorations on vintage instruments to precision fretwork and complete guitar setups, Rauen Guitars delivers the kind of meticulous craftsmanship that comes from decades of working with top guitarists worldwide. The shop’s reputation rests on Denny’s unmatched skill as both an instrument repair specialist and innovator who has shaped modern guitar building techniques.
