Independent shopping perspective
The Korena take
The Grover 3+3 Vintage Deluxe 133 Series tuning machines combine a chrome finish and vintage-styled stamped housings with sealed, lubricated gearing. Their 15:1 ratio gives a slower, more controlled adjustment range for dialing in pitch, and the design eliminates backlash. The posts measure 22 mm long, and the machines are described as handling heavy-gauge strings. They suit an instrument where classic housing styling and precise geared tuning are both part of the brief.
