1 / 7Rubatone TP 06-BK-3L 3R-A Sealed Guitar Tuners, 3L+3R
Rubatone TP 06-BK-3L 3R-A sealed guitar tuners are a six-piece 3-left/3-right replacement set with a black finish and zinc alloy construction. The listing gives a 1:14 gear ratio and describes compatibility with most acoustic or electric guitars, but fit depends on matching the guitar’s mounting dimensions.
At a glance
- Six sealed machine heads arranged as three left and three right tuners.
- Zinc alloy construction with a black finish and half-moon buttons.
- The stated 1:14 gear ratio is intended for tuning adjustment.
- Listing specifies a 10mm machine-head hole and also provides post and mounting-spacing measurements.
Pros and cons
Pros
- The 3L+3R configuration suits instruments requiring three tuners on each side of the headstock.
- The listing gives several fit dimensions, which can help compare the set with existing hardware before purchase.
- Ferrules, screws and threaded bushings are listed alongside the six machine heads.
Cons
- The 1:14 ratio is a relatively coarse specification for players seeking a finer adjustment ratio than this set offers.

What to know before buying
- Compatibility is described broadly as covering most acoustic and electric guitars, not every model. Compare the required 10mm hole, 6mm post diameter, 24.5mm mounting-hole spacing and 22.5mm total height with the instrument before ordering. The color may vary slightly by display and measurements may have manual-measurement deviation.
Who is it for?
A good fit for
- Replacing a 3-left/3-right set of guitar tuners when the existing mounting dimensions match.
- Guitar owners looking for black zinc alloy sealed tuners with the listed small hardware included.
Less suited to
- Guitars with six-in-line or other non-3L+3R tuner layouts.
- Buyers who need a confirmed fit for a specific guitar model without checking the mounting dimensions first.

Aggregate ratings lean positive, with a smaller three-star portion also present. This is a small rating sample and does not establish why customers rated the tuners as they did. For buyers, the listed 3L+3R arrangement and fit dimensions are more useful for judging suitability than the rating alone.
