**String Spacing Rule: Fast, Accurate, and Easy String Spacing**
1. **Introduction**
- The String Spacing Rule is a laser-etched stainless steel tool that provides accurate string spacing without calipers, calculators, or shop rulers.
- It automatically calculates proportional slot spacing for any stringed instrument, ensuring optimal feel and playability.
2. **Key Features**
- **Proportional Spacing**: Compensates for string diameters from treble to bass, preventing thicker strings from feeling crowded.
- **Fast and Easy**: Slotted design allows for quick marking of string positions directly onto the nut using a scribe or pencil.
- **Versatile Use**: Suitable for nut slotting, notching bridge saddles, laying out bridge pin holes, and notching archtop bridges on guitars, basses, mandolins, banjos, and violins.
3. **How to Use**
- Mark the outer string positions on the nut.
- Slide the rule over the nut to align with the marks and scribe or pencil the remaining string positions.
- The rule does the math, eliminating the need for measuring or calculating.
4. **Benefits**
- **Accuracy**: Laser-cut slots ensure precise spacing.
- **Flexibility**: Made from flexible stainless steel that conforms to both flat and arched surfaces.
- **Included Instructions**: Easy-to-follow guide for various applications.
5. **Applications**
- Nut slotting on guitars, basses, mandolins, and banjos.
- Notching bridge saddles and bridge pin holes.
- Laying out bridges on archtop guitars, banjos, mandolins, and violins.
