Graph TechRatio 6-In-Line Electric Guitar Tuning Machine Heads Black 6 String
Independent shopping perspective
The Korena take
A black, right-handed locking Ratio tuner set for electric guitars with six inline machine heads. Its calibrated gear ratios are designed so each string responds predictably to tuning changes, with a half-turn corresponding to one semitone. The two-pin casing can be fitted on its own or paired with the four included brushed-aluminum InvisoMatch plate sets, which are made to use existing screw mounting holes on most guitars. Check the headstock layout and 10mm peg holes before ordering.
Strong match
Who this is for
- A right-handed electric guitar with a six-in-line locking-tuner replacement project.
- Using existing headstock screw holes with an included InvisoMatch mounting-plate set.
- Players who want the stated half-turn-to-semitone Ratio tuning relationship.
Consider the trade-offs
When to look elsewhere
- Left-handed electric guitars.
- Headstocks without a six-in-line layout or 10mm peg holes.
