A flip tuning levers device that does not put added stress on a plurality of guitar strings to get them out of tune. The flip tuning levers device includes a plurality of levers, a plurality of vertical shafts, a plurality of shims, a horizontal shaft, and a base plate. The levers each include a handle, a rotating pin joint, and an upside-down cylindrical-shaped indentation. The base plate includes a plurality of apertures that include a first set of apertures that accommodate receiving a plurality of fasteners and a second set of apertures that accommodate receiving the distal ends of each of the vertical shafts, the first set of apertures correspond with a plurality of preexisting holes disposed on a headstock of the guitar. The flip tuning levers device is made from a three-dimensional printer for accuracy and cost-reduction or is made of titanium for strength and ease of fabrication.

A modular and customizable construction for a guitar is disclosed. The construction may include a substantially flat metal guitar base plate that couples to interchangeable guitar components, such as a guitar body, a fretboard, and guitar string tuners. Further provided is a moveable nut that is used to adjust guitar string scale length via nut blocks that are separately adjustable relative to one another. Even further provided is a computer program product that allows for development of custom fingerboards that cater to a specific player's requirements and are optimized for alternative tunings and temperaments.

A stringed instrument tuner that senses the vibration of all the strings of the instrument independently and simultaneously via ultraviolet reflective light sensors that are immune to interference from ambient alternating-current lighting. The pitches of the strings are then measured continuously in real-time and transmitted wirelessly to a receiver that simultaneously graphically displays how far out-of-tune all of the strings are so that the musician can instantly see which strings need tuning and tune them quickly. The receiver may be a smartphone, smartwatch, smart glasses, computer, self-tuning system, or a dedicated wearable receiver-display unit.
