Independent shopping perspective
The Korena take
Nickel Grover Sta-Tite U98-18 machines provide an open-gear 18:1 setup for careful ukulele tuning changes. Their die-cast plate is described as lightweight, and the ebony button options can be exchanged to change the appearance. They are made as a U98-18-series drop-in replacement, but the installation still calls for a measurement check: the post reaches 20 mm to its hole and measures 25.2 mm overall.
Strong match
Who this is for
- Updating a U98-18-series ukulele with matching tuner post measurements.
