Ratio tuning machines are one of the most significant upgrades for your guitar, second to replacing pickups or electronics. When you try Ratio for the first time, you will notice a substantial difference in the tuning precision of every string, especially when compared to (literally) any other tuner.

Thanks to the InvisoMatch mounting system, installation takes just minutes, requires no modifications for nearly every guitar, and is simple enough for anyone comfortable using a screwdriver & a small wrench to do.


This set of PRL-8341-C0 is finished in chrome with vintage style buttons for installation on Les Paul or other style guitars which have 3 tuners on each side of the headstock; known as 3+3 or 3x3 configuration:

3+3 Configuration Headstock
Shown: 3+3 Vintage Gold w/ Premium InvisoMatch
Installation Plates for 90 Degree Screw Hole - Gold

A variety of standard un-finished aluminum InvisoMatch installation plates are included. Premium InvisoMatch installation plates are available separately in both chrome and nickel finishes for a more elegant look, if desired.


Ratio® tuning feels natural. You don't have to think about which string you are tuning because they all feel and respond the same. No more overshooting the Low E or G. No more twisting away on the High E or D string. Open tunings have never been easier. String gauges such as light top, heavy bottom are no problem with Ratio®; they still do the same precision tuning. 

Ratio InvisoMatch Mounting Plates are the easiest approach to installing Ratio Tuned Machine Heads on your guitar. Simply select the installation plate design that matches the screw/pin hole location of your factory installed machine heads, then follow the three step process described in the product guide. You’ll be up and running within about seven minutes
