The Bigsby B700 Vibrato Tailpiece for Arched Top Electric Guitars is for owners of arch top Les Paul and semi-hollow style guitars who want to add the classy look and great usability of a Bigsby tremolo! With easy installation which requires very little modifications to your instrument, the B700 is a no-brainer for players who want an easy upgrade.
The top mount tremolo 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 B700 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.
