Born and raised in central Maine, John Leadbetter started playing the saxophone in the 3rd grade. He quickly discovered his love for music, and the saxophone. By the age of 16, John had also picked up the flute, and the clarinet, and was performing music professionally all around the State of Maine. While attending the University of North Texas for a Jazz Saxophone Performance degree, John toured the US and Europe performing with the 1 O'clock Lab Band. In 2008 John was the 1st Place winner at the North American Saxophone Alliance Jazz Saxophone Competition. In that same year, John became very interested in musical instrument repair. He began an apprenticeship with Ann Macmillan while studying at UNT and found his love for craftsmanship and attention to detail in instrument repair. After relocating to New York City, John apprenticed and honed his craft further under the guidance of such technicians as Josh Landress, and Phil Unger, and Kristen Bertrand. This lead to the creation of JL Woodwind Repair.
