Independent shopping perspective
The Korena take
Built for precise ukulele tuning, the Grover U99-18 machines use an 18:1 ratio to make small pitch corrections at the peg. Their open-gear layout and ebony buttons give the set a classic-looking profile, paired here with a nickel finish. The 21 mm posts provide a specific headstock mounting point to verify, and each machine head is listed at 0.9 oz. A practical option for keeping tuning work deliberate in practice or before a performance.

Who this is for
