Dave Dunwoodie is the founder of Graph Tech Guitar Labs in Canada and has pioneered several products during his career in the music industry. With the popularity of tremolo guitars, the need for pencil lead in the nut slots was growing. Dave experimented with a variety of composite guitar nuts designed to eliminate string binding. He engineered the world's first self-lubricating nut. Today Graph Tech Guitar Labs also produces saddles bridge pins, bridges and pickup systems. Dave continues to innovate!
