John Guarino

Johnson String Instrument

We have served the Greater Boston string-playing community since 1976. Together with JSI's Guitar Shop and Carriage House Violins, we form New England's largest stringed instrument company, here to offer our customers—beginners through concert artists—the very best in bowed and fretted instruments sales and service. We are one of the first and most prominent internet resources for string players. Our instruments are acquired from a variety of local and international sources, including the major auction houses, collectors, private sale, and consignment.
