Built with a solid Sitka spruce top and solid African mahogany back and sides, the M-140’s 24 ¾” scale length and 1 ¾” nut width on a vintage shaped Guild neck make this concert size guitar easy to play. The M-140 features an Indian rosewood fingerboard and bridge, bone nut and saddle, mother-of-pearl rosette, and period-correct tortoiseshell pickguard. This model also showcases Guild’s iconic Chesterfield headstock emblem reminiscent of 1960s Guilds, and includes Guild’s new lightweight polyfoam case. Available in Natural gloss finish, or with a Fishman Sonitone pickup.

Learn More About the Westerly Collection

The Westerly Collection pays homage to an important period in Guild’s early history, when Guild outgrew the beloved Hoboken, New Jersey factory, and moved production to Westerly, Rhode Island in 1967. Finding a home in a former furniture manufacturing building, Guild took advantage of the additional space the new location had to offer, and improved upon the production layout left behind in Hoboken.

With a fresh start, highly skilled employees, and plenty of room to grow, Guild flourished. It was not long before the Westerly factory became renowned for exceptional craftsmanship, quality, and the introduction of many beloved Guild acoustics. The dedication to innovation was apparent, with meticulous attention to detail. Inspired by this golden era, the Guild Westerly Collection carries on the tradition of impeccable workmanship and unwavering excellence by incorporating high-quality materials and classic Guild designs into each instrument.
