RATIO® patented gear technology
RATIO® - Calibrated Machine Heads incorporate different string gauges into the tuning equation.

From Low B to G - 48:1, 36:1, 30:1, 20:1, 18:1.

We balanced the gear ratios to each string simplifying the tuning process.

With RATIO®, a half-turn is a semi-tone!

Every string reacts the same to any tuning adjustment. Predictable, precise tuning, on every string.

    Fantastic!

    Purchased to replace a set of stock Gotoh tuners on a fretless Renaissance RB-5. Super easy install, and it made tuning faster, more precise, and more stable. Was especially noticeable on the low B string.

    Top Quality

    Exceptionally well-made and beautifully designed. Unfortunately, the G tuner I received is out of sync, but their customer service team was quick to respond and offer a replacement part. Great buying experience.
