PRODUCT DESCRIPTION
- The Graph Tech PRN-3411-N0 Ratio tuning machines are specially designed for acoustic (western) guitars. Thanks to the open construction and skeleton knob, tuning is easy and comfortable. Each string has a specific ratio, so that a half-turn of the knob gives a semitone change, ensuring faster and more precise tuning. The 3 + 3 design is suitable for most standard acoustic guitars and comes in a nickel finish.
