GROVER 102SV Roto SB Guitar Tuning Machines Black Chrome

The Grover 102SV Roto SB Guitar Tuning Machines bring a classic look and serious tech to your instrument. Inspired by old "milk bottle" Rotomatics, these tuners have clear caps so you can see the gears working inside—just like the back of a skeleton watch. Each set comes with sealed gears and a special oil inside that keeps everything smooth for years. The 18:1 gear ratio lets you make tiny tuning changes, so your guitar stays in tune longer. You can adjust how hard or easy the tuners turn by changing the tension screw. These tuning machines fit guitars with a 25/64" post hole and can handle thick strings up to .074". All the hardware you need comes in the box.

Grover Design Supports Reliable Tuning and Easy Adjustments

Players who swap these tuning machines onto their guitar get real control over tuning. The tight gear ratio helps you set each string just right—no slipping or skipping notes. The sealed gears mean you don’t have to worry about dirt or rust slowing things down. If you play a lot, these tuners keep your guitar sounding solid, even after hours of practice. Adjusting the tension screw can make tuning faster or slower, depending on how you like it. GROVER tuning machines help you fix broken tuners or upgrade older gear. Good tuners keep your guitar sounding sharp every time you play or record.
