Michael Keller began making guitars in 1975 under the guidance of Jeffrey Elliot. He was immersed in the Portland, Oregon luthier scene in 1976 and met Richard Schneider, Jimmy D'Aqustio, Michel Gurian and Robert Lundberg. His focus as a builder is to create acoustic guitars that players enjoy and he offers a range of instruments from a massive 18-inch jumbo guitar to a half-sized baby guitar - along with countless options.
