Rockin Bob has been in the guitar business for over a quarter century. His small but well-stocked Davis Square shop is packed with new, used and vintage guitars, as well as amps, audio equipment and a small selection of sheet music. If it has strings, Bob sells it–and he can fix it. In addition to guitar and amp repairs, Bob's visitors may also find the occasional banjo, ukulele or mandolin. Rockin Bob says his shop puts an emphasis on personal service and is a place where you can find a "great deal on a great guitar."
