GRAPH TECH PRL9721-B0 6 IN LINE RATIO ELECTRIC LOCKING MACHINE HEADS (STAGGERED POSTS) – (SELECT FINISH AND BUTTON STYLE)
SCIENCE BEHIND RATIO:
RATIO® patented gear technology
RATIO® – Calibrated Machine Heads incorporate different string gauges into the tuning equation.
From Low E to High E 39:1, 24:1, 20:1, 35:1, 20:1, 12:1.
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.
