## Description

Solid brass construction and a black finish give these Dopro tuner bushings a vintage-style fit for guitar hardware. This version measures 6.5mm inside diameter and 8.8mm outside diameter.

They’re designed for vintage-size tuner installations, including guitars such as Strat, Tele, and Les Paul models. The press-fit, drop-in style supports a straightforward installation.

Choosing the correct bushing size helps match the tuner posts and existing headstock holes. These bushings are intended for vintage-size holes, not modern 10mm tuner holes.

## Tech summary
- Type: Vintage-size guitar tuner bushings
- Material: Solid brass
- Color: Black
- Size: 6.5mm inside diameter × 8.8mm outside diameter
- Installation: Press-fit, drop-in

## Requirements
Match the bushing to both the tuner’s string post and the existing hole in the guitar’s headstock. Vintage headstocks commonly use 5/16" (8mm) or 11/32" (8.5mm) tuner holes, this bushing’s 8.8mm outside diameter is intended for the corresponding vintage-size fit. It is not intended for modern 10mm tuner holes.

The 6.5mm inside diameter is suited to most USA vintage tuners, Kluson vintage tuners with 6.3mm string posts, and Gotoh SD Series standard vintage tuners. It is not the specified fit for Gotoh locking tuners. Measuring the post and headstock hole before selecting bushings helps ensure the parts match. If you’re choosing between vintage-size hardware and bushings for a modern 10mm opening, this is the vintage-size option.

## Getting the most from it
Use these bushings when fitting compatible vintage-style tuning machines to a guitar headstock with vintage-size tuner holes. For example, when replacing or setting up vintage-style tuners on a Strat-, Tele-, or Les Paul-style guitar, the 6.5mm inner diameter corresponds to the tuner post, while the 8.8mm outer diameter corresponds to the headstock opening. This lets you make the fit decision using the two measurements that matter rather than relying on the guitar’s model name alone.

The solid brass construction and finished surface provide a purpose-made ferrule for the tuner installation. The bushings are described as burr-free and easy to install, with a press-fit design that drops into a compatible opening. Check the measurements of the tuner posts and existing holes first, then select the bushing size that matches your setup. This is especially useful when working with vintage tuners, since the right inside and outside diameters help avoid choosing a part based only on appearance.

## Final verdict
For a vintage-style guitar setup that calls for a 6.5mm tuner-post opening and an 8.8mm headstock-hole fit, these black solid brass bushings provide a clear, specific match. Their press-fit design and compatibility with many USA vintage tuners, Kluson vintage tuners, and standard Gotoh SD Series vintage tuners make them a practical choice for fitting the appropriate tuning machines to vintage-size headstocks.
