Johann (Hans) Brentrup has been a woodworker all his life and has been making guitars and mandolins  since the 1970’s. For a period in 1990s he began building mandolins exclusively, building over 250 mandolins and mandolas, earning the reputation of being one of the finest mandolin builders in the United States. In the early 2000’s Hans returned to building finger style guitars. His instruments are heavily influenced by guitars of the 1920’s. He finds Larson Brothers, Oscar Schmidt Stella and Holzapfel instruments particularly influential, and has taken some of their innovations and combined them with his own design elements to produce some of the finest new old time guitars available. Hans’ guitars feature highly arched backs and tops are cylindrically arched. Laminated wood bracings, tone tubes, X, ladder and hybrid bracings, and hand made purflings are some of his other favorite features.
