Model Overview 

These Göldo Excenter Adapter Bushing for Jazzmaster (MFG# HJM8N) sleeves allow for the installation of Tunematic, roller, and other M4 grub screw–mounted bridges on offset guitars—perfect for upgrading vintage and modern instruments alike.

• 9mm bushings are designed for guitars with 9mm bushing diameters, such as most Fender Jazzmaster models.
• 8mm bushings (BP-3937-000) are intended for certain Asian offset models with 8mm bushings.

Installation is simple: insert the appropriate adapter sleeve into the existing bushing, then install your preferred Tunematic or Roller bridge using the necessary accessories listed below.  Not compatible with import tunematic bridges using larger mounting posts.
This upgrade eliminates common Jazzmaster bridge issues:

• No more strings jumping from the saddles
• Fuller tone
• Improved attack
• Enhanced sustain

The bushings are eccentrically threaded, allowing for precise bridge positioning via simple rotation—no additional tools required.
