What Size Are the Headstock Holes for Tuners on Guitar Kit World Kits?Updated 8 days ago

Most of our DIY guitar kits come with 10 mm tuner holes pre-drilled in the headstock . This is a standard size that fits most modern tuning machines.

Why This Matters

The tuner hole size determines what type of tuning machines (tuners) you can install without modification. Most aftermarket tuners from well-known brands are designed for 10 mm holes, while some vintage-style tuners use smaller sizes and may require adapter bushings.

Tuner Compatibility Guide

Here’s a general guide to tuner compatibility with our 10 mm standard headstock holes:

Fits Directly (No Mods Needed)

• Grover Rotomatic tuners (modern style)

• Gotoh sealed tuners

• Schaller M6 tuners

• Fender modern sealed tuners (used on many Strat/Tele models)

• Wilkinson sealed tuners

May Require Adapter Bushings or Slight Drilling

• Kluson vintage-style tuners (often use 8.5 mm–9 mm holes)

• Fender “vintage” tuners (require conversion bushings to fit 10 mm holes)

• Some locking tuners with oversized housings (always check specs)

Custom Requests

If you already have a specific set of tuners you plan to use, check the Product Specifications on the kit page before ordering.

Summary
