vibrato tailpiece
Bigsby B5/B7/B50
The original hand-operated vibrato, made since 1948, in the B5, B7 and B50 versions.
Why it matters
A Bigsby works by hand rather than by a locking mechanism, and the design dates to 1948. The B5, B7 and B50 are the variants named in this line.
Note
The original hand-operated vibrato.
