T. Drew Heinonen’s journey as a guitar builder began as a senior in college with a course entitled “The Physics of Sound,” a lab based study including a wide range of acoustic properities- sound wave propagation, harmonic and overtone relationships and structure, vibrational patterns of plates, strings, and air, instrument and vocal functionality- and culminating in a final project analyzing the resonant frequencies and responsiveness of his own guitar. After completing a Bachelor’s degree in Religion & Philosophy, he enrolled in the Guitar Repair & Building program at Southeast Tech in Red Wing, MN. While a student in Red Wing, Drew met Dana Bourgeois at a voicing seminar and upon graduation was invited to work in the Bourgeois shop in Maine.
