Traditional tuning machines for guitars, basses, and other stringed instruments only allow one fixed height for the string where it attaches to the tuning peg. This fixed “string height” affects the angle the string takes over the nut (the small piece near the head of the instrument). The wrong angle can cause buzzing, tonal interference, tuning instability, or strings sticking in the nut. Current solutions offer little flexibility to adjust this angle for different strings or playing preferences.
Core Features
This invention introduces a tuning machine peg with multiple entry and exit points connected by channels. Each channel allows the string to be attached at different vertical positions (engagement heights) along the peg. By choosing a higher or lower opening, players can change the string’s approach angle to the nut. The peg may also include gears and a tuning button for smooth adjustment, and it’s designed to be easily manufactured by drilling simple holes.
Inventive Step (What’s New)
Unlike conventional pegs with a single string hole, this peg has multiple angled or straight channels positioned at different heights. This simple but clever design lets musicians select from multiple engagement heights—without needing extra parts or complex mechanisms—directly influencing tone, stability, and playability.
Benefits
- Reduces string buzz and tonal interference.
- Improves tuning stability by preventing strings from sticking.
- Allows each string to be optimized individually for best sound.
- Simple, cost-effective manufacturing (can be retrofitted into existing peg designs).
Broader Impact
This adjustable-height tuning peg could improve sound quality and reliability across many stringed instruments—from student guitars to professional double basses—while keeping production costs low. By giving musicians easy control over string angle, it supports better performance, reduces maintenance issues, and enhances musical expression across the industry.
