Upgrade your electric guitar's tuning precision with RATIO® Calibrated Machine Heads, specifically engineered for 3 × 3 tuner configurations found on Gibson and PRS style instruments. These advanced tuning machines represent a significant improvement over traditional single-gear alternatives from manufacturers like Grover, Schaller, Sperzel, and Kluson.

The innovative calibrated design provides superior tuning stability and accuracy, making them an excellent choice for guitarists seeking professional-grade hardware. Each unit features a robust two-pin casing construction that offers versatile installation options.

Installation flexibility is enhanced through compatibility with Graph Tech's Patented InvisoMatch Mounting Plates, though the machine heads can be fitted directly without additional hardware. This adaptability makes them suitable for a wide range of electric guitar models requiring reliable, precision tuning performance.

  • 3+3 Ratio Electric Locking Machine Heads
  • Balanced gear ratios to each string
  • Predictable, precise tuning, on every string
  • Peg holes diameter required: 13/32" (10mm)
  • Button Style: Contemporary
  • Finish: Chrome
