Extraction of braking functions into interlock control sections prevents double strikes while reducing instrument size and manufacturing complexity.
A rotatable string cartridge assembly stores replacement strings inside a guitar body cavity, eliminating the need to carry multiple spare sets.
Porous resin keyboard keys use identical material composition to deliver consistent tactile feedback across white and black key surfaces.
Segmenting the glued tip plug into a removable insert allows DIY re-hairing, eliminating expensive professional labor costs.
A spring assembly applies elastic force to string ends, maintaining pitch stability despite longitudinal elongation or contraction.
A tensioning apparatus raises a string perpendicularly to a fret using lateral biasing force without clamping the neck.
A cam tremolo device uses a manual screw to lock the tailpiece against rotation.
A hollow composite tube stiffener increases torsional stiffness-to-weight ratio, resolving the trade-off between structural rigidity and added neck weight.
Adjustable hammer standby positions reduce striking distance to tone plates, lowering acoustic output volume without requiring precise key force.
Viscoelastic OctaveTouch fretpads maintain tuning stability on 12-string guitars by distributing equal force without detuning.
Nested tubular stands adjust height and forward tilt, resolving pedal accessibility issues across different seating positions.
An offset handle string winder uses bearing units to reduce friction, easing manual turning of tuning pegs.
Resin infusion stabilizes the bow frog to increase sound transmission speed and improve acoustic predictability.
