PRODUCT DESCRIPTION
- Designed for 7-string electric guitars, the Graph Tech PRL-8621-C7 Ratio locking machine heads offer an innovative solution for accurate tuning. Each tuning machine head has its own gear ratio, tailored to the specific string, allowing you to tune quickly and accurately. Thanks to the unique system where a half-turn of each knob changes half a pitch, you enjoy efficient and precise tuning. The chrome finish and contemporary mini knob give your guitar a modern look. The set includes both left and right machine heads for complete installation.
