How to fit an oversized saddle blank to your acoustic guitar
Tools Needed
- Fine sandpaper (220, 400, 600 grit)
- Flat surface for sanding
- Calipers or ruler
- Pencil for marking
- Straight edge
Safety Warnings
- Work slowly - material removal is permanent

- Keep surfaces flat during sanding
Step-by-Step Instructions
1
Measure the saddle slot
Measure the length, depth, and width of your bridge saddle slot with calipers.
2
Sand to width
The most critical dimension. Sand the blank sides evenly on a flat surface until it drops into the slot with light friction.
3
Trim the length
Sand the ends to match your slot length. The saddle should sit flush with the slot ends.
4
Set the height
Height determines your action. Start taller than needed and reduce gradually while testing string height.
5
Shape the crown
Gently round the top edge where strings make contact. A slight radius improves intonation and string break angle.
6
Polish
Finish with 600 grit sandpaper for smooth string contact surfaces.
