Grover Rotomatics 103C Milk Bottle Tuning Machines, Chrome, Pearloid Buttons, 3+3
Grover Original Rotomatics 103C Milk Bottle tuning machines combine the charm of vintage tuners with the reliability of the renowned Rotomatics. Recognisable by their distinctive bottle-shaped housing and elegant pearloid buttons, they add a refined retro touch to electric and acoustic guitars.
With their chrome finish and 3+3 configuration, these tuning machines are ideal for restoring an old guitar, replacing worn tuners or adding a vintage finish to a custom guitar project.
The iconic Grover Milk Bottle style
Grover Milk Bottle tuning machines feature the historic Rotomatics design, with a sealed housing whose silhouette resembles a small bottle.
This version of the 103 series retains the features and design of the Grover Original Rotomatics 102 series, but stands out with its Pearloid buttons and their specific mounting system.
The contrast between the bright chrome finish and pearlescent buttons delivers a particularly elegant look, in the spirit of classic American guitars.
Beyond their appearance, these tuning machines benefit from the proven Grover Rotomatics design, valued for smooth operation and tuning accuracy.

Installation advice and compatibility
These tuning machines fit guitars with a 3+3 headstock configuration, provided that the bore dimensions and mounting screw locations are checked.
For replacement, we recommend comparing the dimensions of the original tuning machines with those of the Grover 103C to avoid unnecessary modifications to the headstock.
Please note for vintage instruments: Grover tuning machines made before 1985 have different threading and post diameters. Components from current models are therefore not directly interchangeable with those from that period.
An excellent choice for recreating the look of historic Rotomatics while enjoying a new set of tuning machines.
