PRODUCT DESCRIPTION
- The Graph Tech PRL-8721-LB0 Ratio locking tuning mechanisms are specially designed for left-handed electric guitars with a 6-in-Line configuration on the high side (treble side). These tuning mechanisms offer a unique ratio for each string, allowing you to tune quickly and accurately. The half-turn of a tuning knob provides a half-tone step, ideal for precise adjustments. The mechanism has a closed construction and a thumb wheel to lock the strings, providing extra stability and better tuning.
