Gibson Thunderbird bridge and tailpiece - mounted on a 1966 ThunderbirdGibson Thunderbird bridge (1960s). Part number BR-750N. This was Gibsons first bass bridge to allow seperate intonation of each string, and was used on the reverse and non-reverse body Gibson Thunderbird, and the Epiphone Embassy from 1963-69. Unlike all other Gibson bass bridges, it required a seperate tailpiece, and was fitted with a damper spring, which acted as a mute by pushing felt blocks (not pictured) against the strings. The bridge posts were short-bushing type, nickel (early), or chrome (later) plated. |
