**Understring Radius Gauges: Fast and Accurate Bridge Saddle Adjustment**
1. **Introduction**
- Understring Radius Gauges are designed for quick and precise bridge saddle adjustments.
- They feature accurately radiused arcs on both top and bottom surfaces, fitting easily under strings.
2. **Key Features**
- **Dual-Surface Design**: Bottom curvature for measuring fretboard radius; top curvature for setting string saddle heights.
- **Low Profile**: Slim shape allows for easy measurement even with strings on, ideal for matching pickup polepiece heights and setting bridge saddles.
- **Versatile Widths**: Standard width (up to 2-5/8" / 66.68mm) for 6-string guitars and most 4-string basses; extra-wide (up to 3-3/4" / 95.25mm) for wider string spreads, including 5-string, 6-string basses, and 7-string or 8-string guitars.
