Since 1974, Kenny Marshall, widely known as the Fret Doctor, has specialized in making guitars play their very best. As a professional luthier and playability expert, Kenny has spent five decades helping musicians bring out the full potential of their instruments.

Trusted entirely through word of mouth, his reputation has been built on precision, care, and a deep understanding of how small adjustments can transform the sound and feel of a guitar. Whether it’s optimizing playability, restoring an old favorite, or preparing for the launch of his own custom guitar line, Kenny’s work is rooted in craftsmanship and a lifelong passion for music.
