In the mid-1970s, Guild pioneered acoustic bass guitar design with the introduction of the B-50 model, which featured a jumbo body shape, arched mahogany back, and an easy to play, 30 3/4” scale length. Guild has reintroduced these vintage features with the new Westerly Collection B-240EF, offering bassists a workhorse acoustic instrument with big tone that plays with ease. Built with a solid Sitka spruce top over an arched mahogany back and mahogany sides, the B-240EF boasts an impressively loud tone that will hold its own during most acoustic jams. It can also be easily amplified with its onboard Guild/Fishman Bass Sonitone system. The B-240EF features a fretless pau ferro fingerboard with maple fret lines, providing a spectrum of sounds ranging from a mellow upright bass vibe to bright and growly Jazz fusion tones. This model also features a pau ferro bridge, slim C shape neck profile, 1 5/8” bone nut and bone saddle, tortoiseshell pickguard, and a mother-of-pearl rosette. Available in Natural satin finish. Also available fretted (B-240E).

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.
