Buying Guide
What should you consider when choosing neck shims? Material matters for tone, resonance, and durability. Maple is popular for tone preservation, while brass offers rigidity for small angle tweaks. Nylon provides durability and flexibility for long-term wear. Ensure the shim thickness and taper fit your bolt-on neck heel and bridge setup. Consider humidity and climate: wood shims can swell or shrink with changes in moisture, while metal shims resist these changes but require careful seating to avoid gaps.
How many shims do you need? Most players start with a 3-piece kit offering 0.25°, 0.50°, and 1.00° tapers. This range covers common neck-angle adjustments and allows precise tuning without over-correcting. If your guitar has a unique heel geometry or you’re adjusting multiple positions, you may prefer a larger set with more granularity. Always verify that the shim sits flush under the neck heel to avoid air gaps and buzzing.
