TonePros Kluson KR3 guitar tuning machines apply the tuner improvement technology of the 33 Series to the vintage 3 on a rail format. Typically you'll find this type of tuner on older '50s classic instruments such as Juniors or Specials. R3 series tuners utilize the classic white round plastic button. For years, many have sung the praises of having the row of 3 tuners connected to the back of the headstock for added resonance transfer. TonePros enhances this tradition with a solid baseplate for each row of 3 tuners.
Completely sealed, these tuning machines feature all titanium internal components and a 16:1 gear ratio. 12/64" shaft size. Retrofit your vintage guitar with no modification.
