Description

Transform your tuning experience with the Planet Waves Auto Trim Locking Tuning Machines. These aren't just any tuners; they're the perfect blend of innovation and convenience for your guitar. By automatically trimming excess string as you tune, they not only save time but also eliminate the annoyance of sharp, protruding string ends that can mar your guitar's appearance or even injure your fingers.

Whether you're a seasoned performer or a budding musician, these tuning machines are designed to enhance your playing experience. Each tuner is equipped with a locking clamp that holds your strings firmly in place, which is especially beneficial for guitars with vibrato systems. This ensures that your instrument stays in tune, even after extensive use. The precise 18:1 gear ratio provides exceptional tuning accuracy, so you can focus on your music, not retuning.

These tuners are crafted for 6-inline headstocks, making them an ideal upgrade for many popular guitar models. Not only do they offer functionality, but they also bring a sleek and professional look to your instrument. If you're looking to replace your tuning machines, choose a solution that offers both practicality and performance.

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Planet Waves Auto Trim Locking Tuning Machines.

Setup and maintenance

  • High E strings have been reported to break during tuning, potentially due to burrs on the locking peg, which can be smoothed with ultra-fine grit sandpaper.

    Source
  • Users report that D'Addario flatwound strings with a 65 gauge low string barely fit through the tuner hole; thicker strings may require machining adjustments.

    Source
  • For those using a Floyd Rose, ensuring strings sit flat against the nut is crucial, potentially requiring a retainer bar adjustment.

    Source

Comparisons

  • Some users prefer Grover locking tuners over D'Addario for reliability, noting fewer string breakages and better performance on guitars like the Epiphone Les Paul.

    Source
  • Sperzel tuners are favored by some for their custom color options and durability, contrasting with D'Addario's perceived higher failure rate.

    Source

Features and functionality

  • The auto-trim functionality may cause issues if not installed correctly, with some owners recommending winding strings around the post like traditional tuners to prevent slippage.

    Source
  • The auto-trim feature allows for tool-free string changes, enhancing convenience by eliminating the need for cutters.

    Source
  • Owners appreciate the smooth and stable tuning experience, noting the speed of string changes as a standout feature.

    Source
  • Some users report that the stud locking the string is weak and can easily break, indicating a potential design flaw.

    Source

User experience

    Source

    Source
  • A long-term owner of the earlier Planet Waves models still appreciates their performance, suggesting possible differences in quality over time.

    Source

Build quality

  • The tuner post holes are 10mm, and the anti-rotation screw requires a 1.5mm pilot hole drilled directly south, not at an angle.

    Source

Use cases and applications

  • Locking tuners may be unnecessary with a Floyd Rose system, as the locking nut already secures the strings.

The Planet Waves Auto Trim Locking Tuning Machines impress with their innovative auto-trim feature, eliminating the need for string cutters and enhancing tuning stability. They are easy to install, offer smooth operation, and maintain tuning excellently. However, left-handed guitarists might face a minor hiccup as they lack a left-side only version, but this can be managed with some workaround. Available in various finishes, these tuners are a practical upgrade, though lefties should plan accordingly. Overall, a highly recommended choice for guitarists seeking convenience and reliability.
