A teenage John Greven built his first instrument, a 5-string banjo, in 1962. Over the last fifty years, he has built over 2,000 instruments and become one of the world’s most in-demand luthiers. On this week’s podcast, we talk to Greven about his unique career trajectory, including his invaluable time working for George Gruhn in Nashville; how he's able to create so many instruments a year; and why so many of his guitars end up in Japan. Greven also talks about some of the magical moments he had with vintage Martin and Gibson guitars during his stint in Nashville. Greven now resides in Portland, Oregon. He is currently at work on his 2,200th instrument, a 000-sized guitar with Brazilian rosewood back and sides.
