We pioneered acoustic bass guitar design in the mid-1970s with the B-50, which featured a jumbo body shape, arched mahogany back, and an easy to play, 30 3/4 scale length. Decades later, these vintage features are back with our B-240E, 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-240E will hold its own in acoustic jams. It can also be easily amplified through an onboard Guild/Fishman Bass Sonitone Bass system. The B-240E features a pau ferro fingerboard and 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 fretless (B-240EF).
