Independent shopping perspective
The Korena take
These black Ratio Tune-a-Lele machine heads are a four-tuner set for ukuleles other than soprano models. Their 6:1 gearing is described as ukulele-friendly and easier to tune, while the larger buttons distinguish this version from the smaller-button alternatives. At 7 g per machine head, the set is intended to keep the instrument balanced rather than headstock-heavy. Installation requires 6 mm peg holes, so the post and bushing measurements deserve a close check first.
Strong match
Who this is for
- Outfitting a four-tuner non-soprano ukulele with 6 mm peg holes.
Consider the trade-offs
