The Bigsby B50 Vibrato Tailpiece for Solid Body Guitars provides smooth and stable whammy use for flat top electric guitars! The Bigsby vibrato tailpiece has become an icon since it was designed by Paul A. Bigsby and is an easy way to give your guitar the great looks and use of a tremolo. The Bigsby B50 vibrato is a top mount unit that allows musicians to bend the pitch of notes or entire chords.
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 B-50 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. The Bigsby is highly controllable within its range of motion and requires little force to operate.
