Key Features and Specifications

The PRN-8441 sets of locking machine heads are specifically designed for right-handed acoustic guitars, featuring a 3+3 tuner configuration. Each set includes a two-pin casing that can be mounted directly or with the included patented InvisoMatch Mounting Plates for a secure fit. The package comes with 4 different sets of brushed aluminium mounting plates, allowing for fast and accurate installation on most guitars. Key specifications include a gear ratio unique for each string position, ensuring one turn equals one tone, and peg holes diameter of 10mm/13/32". The string post diameter is 6mm/0.236", with a length to string hole of 23mm/0.910". Each machine head weighs 38g/0.083lbs, and a set of six weighs 225g/0.496lbs. These heads are compatible with strings up to 72 gauge, and the package includes 6 machine heads, mounting screws, and bushings, as well as 4 sets of aluminium mounting plates.

Practical Uses and Benefits

The GraphTech RATIO Acoustic Guitar Locking Machine Heads are perfect for musicians who demand precision and reliability. Whether you're a professional on stage or a hobbyist at home, these machine heads ensure that your guitar stays in tune, even during the most intense performances. The RATIO® patented gear technology incorporates different string gauges into the tuning equation, offering a balanced gear ratio for each string position. This unique feature allows for a half-turn to be a semi-tone, resulting in predictable and precise tuning on every string. With these machine heads, you can achieve consistent tuning across all strings, enhancing your playing experience and making it easier to produce the perfect tone every time.
