The Korena take

Designed for a right-handed five-string bass with a 2+3 headstock arrangement, this Ratio tuner set uses calibrated gear ratios across the strings. The design is intended to make each tuning adjustment react consistently: a half-turn corresponds to one semitone. Chrome Y-style buttons complete the set. For a clean replacement job, verify that the bass uses the 2+3 layout and has the required 14mm peg holes before installation.
