The Bigsby vibrato tailpiece (or Bigsby for short) is a mechanical vibrato device for electric guitar designed by Paul Bigsby and produced by the Bigsby Electric Guitar Company (an independently operated subsidiary of Fender Musical Instruments Corporation since Bigsby’s purchase from Gretsch in January 2019).
Bigsby was inspired to create a new vibrato system after being tasked by Merle Travis to repair the Kauffman Vibrola vibrato on his Gibson L-10. The first system went to Travis in 1951. By the mid-1950s, Bigsby had ceased production of his own guitars to focus on producing a range of vibrato tailpieces.
