The full story

Description

The Graph Tech Ratio Machine Heads - 3+3 GTR831 are expertly designed for both acoustic and electric guitars, ensuring reliable tuning stability for musicians. With a classic 3-a-side configuration, these machine heads provide smooth and precise tuning, making them ideal for steel-string guitars.

Key features include:

- Suitable for 6-string acoustic and electric steel-string guitars

- 3-a-side design for traditional headstock layouts

- Durable construction for long-lasting performance

- Patented Ratio multigeared technology for consistent tuning response

- Easy installation with pre-packaged InvisoMatch mounting plates for compatibility with various screw configurations

Graph Tech has innovated the tuning process by incorporating different gear ratios for each string position, allowing for intuitive and efficient tuning adjustments. One turn of the tuner results in about one tone change across all strings, simplifying the tuning experience.

These machine heads are an excellent choice for guitarists seeking dependable tuning hardware that combines functionality with a timeless design.
