Independent shopping perspective
The Korena take
For a Squier or Fender bass, the chrome TK-7817 OGT is a direct-replacement set of four small-post, open-gear tuners in a 4-in-line pattern. Its cast base plate is intended to give the headstock-back contact area more stability than a conventional stamped design. The worm-gear tension adjustment uses a hex head to help curb slip while making tuning movements smoother and more precise. An extended key stem gives the controls more clearance around the headstock.
Strong match
Who this is for
- Direct tuner replacement on a Squier or Fender bass with four small posts in line.
- Bass setups where additional space around the headstock tuning keys is needed.
