Find Your Bass Neck's True Relief: The Notched Straight Edge Guide
When setting up a bass guitar, a straight edge is essential for checking neck relief, but a notched version like this Made in USA tool is specifically designed to clear the fret crowns and rest directly on the fretboard. This allows you to measure the neck's true curvature without interference from uneven fret wear, making it a precision instrument for serious luthiers and DIY players.
Key Considerations Before Buying
- Ensure the straight edge is long enough to span at least 12 frets on your bass neck; this tool's length is typically 12-18 inches, which covers the critical first 12 frets for most 34-inch scale basses.
- The notches must be precisely cut to match common fret wire sizes; check that they are deep enough to clear medium jumbo frets without touching, as shallow notches can give false readings.
- Material and flatness are critical: high-carbon steel or hardened stainless steel with a certified flatness tolerance of ±0.001 inch ensures repeatable measurements, unlike cheaper aluminum tools that can warp.
What Our Analysts Recommend
Look for a straight edge that is clearly marked as 'precision ground' or 'certified flat' with a stated tolerance. The notches should be evenly spaced and deburred to avoid scratching the fretboard. A laser-engraved scale or measurement markings add utility for documenting neck relief values.
Tools Market Context
Market Overview
The market for luthier tools has expanded with the rise of DIY guitar maintenance, but many budget straight edges are made overseas with inconsistent quality. Made in USA tools like this one target professionals and discerning hobbyists who prioritize accuracy over cost, though they come at a premium.
Common Issues
Common problems include straight edges that are not truly flat (often due to poor manufacturing or shipping damage), notches that are too shallow for modern fret wire, and tools that rust easily without proper coating. Some cheap versions also have rough edges that can mar a fretboard.
Quality Indicators
Quality indicators include a manufacturer's flatness certification (e.g., ±0.0005 inch), a protective coating or stainless steel construction to prevent rust, and positive reviews from experienced luthiers who verify the tool's accuracy with a surface plate. A notched design that fits both 4-string and 5-string basses is a plus.
Review Authenticity Insights
Grade B Interpretation
With a Grade B and an estimated 10% fake review rate, this product's review pool is mostly trustworthy but has a small minority of potentially unreliable feedback. The 173 reviews with a 0.00 rating likely indicate either a new listing or a product with no verified sales yet, which warrants caution.
Trust Recommendation
Given the low rating and lack of verified feedback, prioritize reviews that describe specific testing methods (e.g., 'I checked this against my machinist's straight edge') and ignore vague praise. The 10% fake rate is manageable, but cross-check with independent luthier forums for real-world experiences.
Tips for Reading Reviews
For tools like this, focus on reviews that mention flatness verification, notch depth relative to fret wire, and any issues with rust or accuracy. Avoid reviews that only say 'works great' without technical details, as they may be from non-experts or fake accounts.
Expert Perspective
This Made in USA notched straight edge is a niche tool designed for precision bass setup, ideal for luthiers who need to measure neck relief without fret interference. However, the 0.00 rating and lack of verified reviews suggest it may be a new or low-volume product, so buyers should verify the manufacturer's quality claims independently. The 10% fake review rate is low, but the absence of substantive feedback makes it a higher-risk purchase for beginners.
Purchase Considerations
If you're a professional luthier or advanced hobbyist who values American-made precision, this tool could be a solid investment, but only if you can confirm its flatness tolerance. For casual users, a cheaper imported straight edge with verified reviews may be more practical.
Comparing Alternatives
Shoppers should compare this with other notched straight edges from brands like StewMac or Music Nomad, which have established reputations and extensive user feedback.
