Disclosed is an improved vibrato device. The typical components of the disclosed device include, but are not limited to, a dual spring-loaded lever arm 10. The lever arm 10 is intended to sit separate and away from the instrument's strings 70 to allow for the user to manipulate the instrument's vibrato while playing by manually moving the lever arm 10 closer to or farther from the instrument. The lever arm 10 connects to the dual spring system 15; the dual spring system 15 houses the vibrato device's springs that allow vibrato manipulation and sits attached to the tremolo system's tailpiece 60, which anchors the vibrato device to the instrument, and the pivoting metal bar 40. The pivoting metal bar 40 is the strings' 70 anchor-point at the base of the instrument, and the bar 40 pivots in response to the lever arm 10 being raised or lowered. When the bar 40 pivots, it either lessens the strings' 70 tension when the lever arm 10 is lowered or increases the strings' 70 tension when the lever arm 10 is raised.
A spring system for tuning a string of a musical instrument, said spring system including an open tuning stop, said spring system comprising a compression spring (3) that is located between a top plate (4) and a base (1), where the top plate (4) is threaded to receive a screw (2) and where the spring (3) exerts an upward force on the top plate (4) relative to the base (1) until a shoulder of the screw (2) abuts the extent of a screw receptacle in the base (1), wherein said abutment puts a string of a musical instrument in an open tuning position.
An adjustable handle for a vibrato device of a musical instrument, said adjustable handle comprising:
