Abstract:
An improved Bigsby vibrato device for a guitar. The improved device includes a mechanical stop which ensures that the device returns to its original neutral position after being used, thereby preventing mistuning of the guitar. The mechanical stop may be a hard stop which prevents the device from increasing tension on the guitar strings (thereby raising the pitch) beyond the neutral position, or it may be a spring stop which allows the user to increase the tension on the strings beyond the neutral position by pulling upward on the device arm with a force sufficient to overcome the spring stop.

Claim (Index 1):
A vibrato device for a guitar comprising:\n a frame configured for attachment to a guitar body; a rod supported by the frame and rotatable about its longitudinal axis relative to the frame; an arm attached to the rod such that movement of the arm causes rotation of the rod about its longitudinal axis; and a stop associated with the rod and configured to make a contact at a neutral position, wherein the stop comprises a spring stop further comprising: a stop plate attached for rotation with the rod; a pivot plate urged against the stop plate by a spring attachment wherein the pivot plate makes contact against the frame to establish the contact at the neutral position; and wherein the pivot plate is urged away from the stop plate by compression of the spring attachment when the arm is moved past the neutral position to a raised-pitch position.
