Bigsby B70 Vibrato Tailpiece for Arched Top Electric Guitars
The Bigsby B70 Vibrato Tailpiece for Arched Top Electric Guitars provides that classic look and feel to your thin acoustic/electrics or arched top guitars such as Gibson ES335, Les Pauls or similar guitars! Since it was designed by Paul A. Bigsby, this vibrato has been incredibly popular among guitarists of all types. The Bigsby B70 vibrato is easy to install and requires very little alteration to your instrument.
The top mount unit allows musicians to bend the pitch of notes or entire chords with their pick hand for various effects. The Bigsby was the first successful design of what is now called a whammy bar or tremolo arm, although vibrato is the technically correct term for the musical effect it produces. The arm of the Bigsby is spring loaded and attached to a pivoting metal bar, around which the strings of the guitar are installed.
In the neutral or unused position, the pressure of the spring counterbalances the pull of the strings, resulting in constant pitch when the strings are played. When the arm of the Bigsby is pushed down towards the top of the guitar, the bridge rocks forward causing the strings to loosen, lowering their pitch. When the arm is released, the strings return to normal pitch. The arm may also be lifted slightly to raise the pitch of the strings.
