Description
Part of Allparts' Top Lock™ line — tuning keys engineered specifically for players who demand "lock-solid" tuning stability and fast string changes, without sacrificing the precision and smooth feel of the companion Top Tier™ line. Where Top Tier delivers professional-grade non-locking performance, Top Lock adds a locking mechanism on top of that same engineering standard, built for aggressive players who push their tuning hardest.
This model — the Mid-Size 3x3 — is Top Lock's compact option for Gibson-style headstocks, without giving up any locking function or tuning stability compared to the full-size Top Lock keys. It's the sleek, modern counterpart to Top Lock's more traditionally-styled Vintage 3x3 locking tuners — same lock-solid engineering, aimed at a more contemporary build.
What the locking mechanism actually gets you: an easy-to-use lock wheel on the back of each key clamps the string in place after just a wrap or two, instead of the many winds a standard tuner needs — faster string changes and dramatically less tuning drift from string slippage at the post.
What else makes these genuinely "Top Lock" rather than a basic locking tuner:
- Internal tension washer — fitted at the base of the string post to eliminate "post wiggle," the small amount of play that robs sustain and undermines tuning stability
- Nylon washer and steel button shaft — deliver a smooth, precise feel to the locking action itself
- Sealed, die-cast zinc housing — keeps moisture, hand sweat, and grime out of the internal mechanism over years of use
- Purpose-built compact housing — engineered for smaller headstocks, not a full-size tuner with a smaller shell
Fitment note: requires 10mm tuning key holes.
