Understring Leveler

The Understring Leveler is a tool that lets you level guitar frets with the strings still on. Here’s a simple summary:

1. **What It Does**:
   - You can level frets without taking off the strings.
   - It works with 1" wide 3M Stikit Gold Abrasives for fast setup and leveling.

2. **Why It’s Great**:
   - It levels frets at the exact tension the neck has when you play the guitar.
   - It fits under and between the strings while the guitar is tuned.
   - It’s thin (5/64" thick), so it glides easily under the strings.
   - You can see and fix any bumps or uneven spots while the neck is under tension.

3. **Different Sizes for Different Jobs**:
   - **4.5" Fretbar**: Good for fixing specific problem frets anywhere on the neck. Also great for creating a special shape on acoustic guitars.
   - **9" Fretbar**: Works for small necks like ukuleles and mandolins. Can also level full-scale necks and fix specific frets.
   - **18" Fretbar**: Levels the entire neck quickly and evenly. It’s safe to use without hitting the nut, saddle, or other parts.

With the Fretbar, you can level frets easily and accurately without any surprises!
