A self-locking tuner is used to tune the strings of a musical instrument. The self-locking tuner is disposed in a headstock of the stringed musical instrument. The self-locking tuner has an inner string post, outer string post disposed over the inner string post, locking pin extending above the inner string post and through the outer string post to the opening, and insert disposed around the outer string post. Alternatively, a cast housing is disposed around the outer string post with a stop to unlock a string. The string extends through an opening in the outer string post. The insert or cast housing has a stop to unlock the string. The outer string post has a rotational stop which contacts the stop to unlock the string. The insert is disposed in a headstock with the tab disposed in a slot formed in a surface of the headstock.

A pitch changer system for a string musical instrument, including a lever assembly, a rotating saddle assembly, a swing plate, and a lever tensioning assembly. Applying force to move the lever in a first direction forces a bell crank matingly coupled to the lever into rotation such that a coupling system of the lever tensioning assembly causes the swing plate to force a rotating saddle of the rotating saddle assembly into rotation to elongate and thereby temporarily change the pitch of a string coupled to the rotating saddle.

A stringed instrument, such as an acoustic, electric, or semi-acoustic electric guitar or bass, can employ a stringpath assembly that consists of a tail structure connected to a head structure via a plurality of strings with the tailpiece consisting of a body disposed between a bridge mechanically fastened to a tailpiece with each string of the plurality of strings continuously extending from the bridge through the body to the tailpiece to efficiently capture vibration of the plurality of the strings.

A string tensioner is configured to apply a substantially constant tension to a string over an operational range even if such string stretches and contracts over time. Tension is provided by a spring. Flexers can attach the spring to a force modulation member and a frame. The flexers preferentially bend out-of-axis so that the spring does not bend out-of-axis when the force modulation member rotates. A dampening system can slow the force modulation member's response to vibrational forces. A flexible stop can prevent rotation of the force modulation member beyond a desired point, but flexes to remain in contact with the force modulation member over a small range of movement.
