Independent shopping perspective
For a right-handed five-string bass using a 3+2 tuner layout, this black Ratio machine-head set pairs separate calibrated gear ratios with each string. The intended result is a consistent tuning response across the set, with a half-turn corresponding to one semitone. Its 14mm peg-hole requirement and 26.1mm string-post measurement make headstock dimensions worth checking before any installation work begins.
