The Badass OGT's offer several improvements from the original design without straying too far from their classic look. Featuring a cast-base plate rather than the traditional stamped-design, it improves stability and surface contact with the back of the headstock. The hex-head worm-gear tension screw helps reduce slip, ensure a smoother feel and improve tuning accuracy. This tuner has a lengthened key stem that offers better clearance around the headstock.

    The Leo Quan Badass OGT Open Gear Large Post 4-In-Line Bass Tuning Machines are designed as direct replacements for many Fender® and Squier® basses, featuring a 14mm post and requiring an 18mm headstock hole (18.4mm OD) . While the exact dimensions of the Ray4's stock tuners aren't specified, it's possible that the Badass OGT tuners could fit. However, modifications such as re-drilling mounting holes or using adapter bushings might be necessary. It's also worth noting that some users have reported challenges when replacing tuners on Sterling basses, including potential headstock damage during bushing removal .

    Can these tuners be compatible with Fender and Squier basses? If not, what should I go with? I'm trying to find black tuning machines.

    The OGT Open Gear Large Post 4-In-Line Bass Tuning Machines may or may not be directly compatible with Fender and Squier basses, depending on a few key specifications. Here's a breakdown to help guide your choice: Key Compatibility Factors Tuner Post Diameter::: Most Fender and Squier basses use 11/16" (≈17.5mm) diameter headstock holes for their tuning machines, particularly on Precision and Jazz Bass models. Verify that the OGT tuners have the same bushing diameter. If they’re too small, they may rattle or require adapter bushings. Mounting Screw Hole Pattern::: Fender-style tuners (especially vintage-style open gear) typically use a 4-screw rectangular pattern. Some aftermarket tuners (including OGT) may have different screw hole positions. You’d need to check if they align, or be willing to drill new pilot holes. Post Length and Gear Orientation::: Make sure the tuner post length suits the headstock thickness of your Fender/Squier bass. Most Fender-style basses use inline 4 tuners (all on one side), so your OGT tuners should match this layout.
