The Graph Tech PRL-8311-B0 Ratio Electric Guitar Locking Tuners in Black.
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. The PRL-8311-B0, is a right-handed set of Locking RATIO Calibrated Machine Heads for electric guitars that use 3 x 3 tuners, such as Gibson style and PRS style guitars.
A great upgrade over single-gear machine heads, such as Grover, Schaller, Sperzel, Kluson, etc. It has a two-pin casing that can be used as is, or with our Patented InvisoMatch Mounting Plates.
