Graph Tech Ratio Electric Locking 6 Inline Staggered Tuners, Black Premium plated InvisoMatch mounting plates in these and other configurations are also available
Manufacturers Part number: PRL-9721-B0
This is a right-handed set of Locking RATIO Calibrated Machine Heads for right handed electric guitars that use 6 Inline Staggered tuners, such as Fender Strat & Tele style guitars (and many other right handed 6 Inline right handed guitars).
RATIO - Calibrated Machine Heads incorporate different string gauges into the tuning equation - we balanced the gear ratios to each string simplifying the tuning process. With RATIO, a half-turn is a semi-tone!
Every string reacts the same to any tuning adjustment. Predictable, precise tuning, on every string.
It has a two-pin casing that can be used as is, or with Graph Tech's Patented InvisoMatch Mounting Plates.
4 different sets of InvisoMatch mounting plates in brushed aluminum are included to make installation on most guitars fast and accurate by using your existing screw mounting holes.
