The 1978 Guild B-50 is a jumbo acoustic bass guitar renowned for its robust acoustic projection and deep, resonant tone. Featuring a solid spruce top paired with mahogany sides and an arched mahogany back, its large body—approximately 18 inches wide and nearly 7 inches deep—contributes to its powerful sound. The mahogany neck, topped with a rosewood fingerboard, offers a comfortable playing experience, while the 30.5-inch scale length provides a familiar feel for bassists. Introduced in the mid-1970s, the B-50 has maintained its reputation as a standout acoustic bass guitar. Includes the original hardshell case.
