FretGuru XT

FretGuru XT

One Tool, So Many Uses…
When a guitar lands on your bench, you need answers quickly.

Is the action correct? Are there high frets causing buzz? How much fret wear is present? Is pickup height properly adjusted? What is the bridge spacing or nut width? 

The FretGuru XT puts the most common measurements you use most into one easy-to-read, durable, pocket-sized gauge.

Whether you're performing a complete setup, evaluating a used instrument, diagnosing playability issues, or prepping for a repair, the XT delivers the information you need in seconds. 

Why Choose the XT?
The FretGuru XT offers expanded functionality over the original design for improved readability, and additional measurement references that help eliminate the need for multiple tools on your bench.

The larger format, increased thickness, and easy-to-read laser-etched markings make the XT comfortable to use during daily shop work, while its expanded measuring capabilities help you quickly diagnose issues and identify specs before making adjustments or ordering replacement parts.

The FretGuru XT is ideal for:

• Diagnosing fret buzz
• Finding high frets before leveling
• Measuring pickup height
• Evaluating fret wear
• Comparing guitar specifications
• Checking nut dimensions
• Identifying bridge spacing before ordering replacement parts
• Identifying pickup spacing before ordering replacement pickups
• Evaluating used instruments before purchase

The FretGuru XT is essential to:

• Professional guitar repair techs

• Hobbyists performing their own setups
• Players maintaining their own instruments
• Anyone evaluating used guitars

Feature Uses

Integrated Four-Sided Rocker
Locate high frets anywhere on the fingerboard with the XT's integrated four-sided rocker. The expanded design covers fret spacing from the first fret through the upper register.

Bridge and Pickup Spacing Reference
Quickly identify common bridge and pickup spacing configurations without reaching for calipers or searching through spec charts. This is invaluable when selecting replacement pickups, bridges, saddles, and other hardware, where spacing compatibility matters.

Nut Width and String Spacing Reference (Metric Only)
Check nut dimensions and string spacing during setup, repair, modification, or replacement-part selection.

Angled Pickup Height and Depth Gauge
The XT's integrated angled depth gauge makes measuring pickup height, saddle height, and other setup dimensions easier than with conventional rulers. Its geometry provides improved clearance around the strings and fingerboard, allowing for quick and consistent measurements.

Fret Height and Wear Evaluation
Built-in fret-height references and wear gauges help you assess fret condition and determine whether leveling, dressing, or replacement may be necessary. This makes the XT particularly valuable when evaluating used instruments or diagnosing playability concerns.
