Graph Tech PRL-8721 Ratio 7-String Locking Guitar Tuners, 7-In-Line

Add some locking tuners to your 7-string guitar! Made for 7-in-line headstocks, these tuners deliver very smooth, even ratios for precise tuning on the fly.

This 7 string set of chrome locking Ratio tuned machine heads for electric guitars use a 7-in-line configuration. It has a two pin casing that can be used as is, or with our Patented InvisoMatch Mounting Plates. Four 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.

Ratio tuned machine heads incorporate different string gauges into the tuning equation. From Low B to High E 48:1, 39:1, 24:1, 20:1, 35:1, 20:1, 12:1. GraphTech calibrated the gear ratios to each particular 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.
