Karl Hoyt made his first guitar in 1978 and his first bass in 1979. Hoyt worked as a psychotherapist for many years while also building basses and guitars on commission in his spare time. In 2008 he got a job teaching woodworking and guitar building to high school children in Cape Cod, Ma. Each year they build about 30 acoustic guitars and 30 electric guitars and basses. Due to the time commitments of teaching he stopped making instruments on commission but planned to resume when he retired from teaching.
