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 enough to overcome the spring stop.
