Independent shopping perspective
The Korena take
Imperial 152 Series tuning machines combine chrome hardware with large butterbean buttons and a 16:1 lubricated gear ratio. They are intended for guitars and offer a straightforward replacement route on most standard guitar headstocks, provided the 25/64-inch post hole and 22.2 mm post length match your instrument. The result is a tuner set focused on precise, efficient adjustment with a distinct vintage-influenced button shape.
