A vibrato device for an instrument, such as a guitar, comprises a base
plate having a forward side with a pivot means and at least one elongated
bridge post fixed thereto. Each bridge post is fixed to at least one of
the strings of the instrument above a top surface of the base plate and
includes a spring fixed below a bottom surface thereof. The spring
generally balances the string tension around the pivot means. A vibrato
handle is fixed to the base plate, and when moved it causes the base
plate to pivot around the pivot means and the effective pitch of each
string is changed accordingly. Yet each string may be tuned against the
string biasing means independently of any other string since each string
has its own spring biasing means.
