Clamping Mechanism: Different designs use spring-loaded triggers, adjustable screws, or levers to hold the strings down. Tension adjustments: Advanced models feature micro-dials or knobs to fine-tune clamping pressure and prevent strings from going sharp or buzzing. Protective Padding: High-density silicone or rubber padding protects the guitar neck and fretboard from scratches and dents. Profile & Material: Built from lightweight aluminum alloy or strong metals for durability without adding neck weight.
