## Overview

The Fret Rocker and String Height Gauge is a precision CNC-milled, aircraft-grade aluminum tool engineered to identify high frets and measure string height with ±0.0005" accuracy.

Hard anodized for durability, this USA-made tool is trusted by guitar techs and custom builders seeking uncompromising quality and longevity.

## Description

If you look in any guitar tech's toolbox you will undoubtedly find two tools that are used in almost every setup and repair - a Fret Rocker and a String Height Gauge. The Fret Rocker is used to identify high frets that are preventing the string action from being set as low as possible. The String Height Gauge is used to make sure the action is set as accurately as possible based on the player's preferences. Since both of these tools fall into the "must have" category, We decided to combine them into one package. Sick of having to set your string action high to quiet your guitar's fret buzz? You're not alone... Most guitars have frets that are a few 1/1000's an inch high when compared with their adjacent frets. You can make your guitar play better in a few quick steps: Step 1 - Use a Fret Rocker to identify high frets Step 2 - Adjust the neck to a flat position, then sand or file the offending frets level. Step 3 - Recrown and polish your frets. There is no better way to take care of Step 1 in this process than using a SkyScraper Guitars Fret Rocker so you can identify problem frets. For the remaining steps, use our Notched Straight Edge and Sanding Beams. To ensure our tools are the most accurate on the market, SkyScraper Guitars' Fret Rockers are CNC milled (not water, plasma or laser cut) out of aircraft grade aluminum. The edges are then checked on a machinist's precision surface plate. The resulting tool has edges that are +/- .0005" over 12". This is a microscopic level of precision that results in accurately detecting imperfect frets. Once the edges are perfectly flat, our Fret Rockers then undergo a hard anodizing process that ensures they will provide a lifetime of service in the hands of any discerning guitar player, repair tech or custom builder. If you want uncompromised quality, this is the tool for you.

Review: Super quality - Great product, and the value is well worth any extra $.
Review: Fret Guru - The Mac Tools of the Industry - If Stew-Mac tools are the Snap On brand in guitar repair, then Fret Guru are the industry's version of Mac tools - EVERY BIT AS GOOD AS SNAP ON BUT LESS EXPENSIVE - thus are a terrific value for the money. I have bought everything Fret Guru sells and have yet to regret any buying decision. The tools are well made, durable, all numbers are visible, and FG stands behind their products. Before you blow your $ on more expensive tools, I suggest trying Fret Guru and their fret rocker works perfectly.

## Features

- DON'T PAY MORE FOR MULTIPLE TOOLS - This one tool measures string height AND locates high frets
- GREAT FRETWORK = EASIER GUITAR PLAYING - Don't let your guitar get in the way of your creativity. A guitar free of fret buzz and with low string action is easier to play and will let you concentrate on making music instead of fighting just to get clean notes
- UNLIKE OTHER TOOLS - This string height gauge is precision machined and accurate within .0005". Many of the off-shore made string height tools cannot even measure string height properly (Yes, we buy them to find out so you don't have to)
- YOU NEED A TOOL THAT IS DEAD FLAT - The only way to properly identify a high fret is to start with a tool that is perfectly flat. These tools are CNC milled then checked on a machinist's surface plate to ensure the edges are +/- .0005" flat over a 12" length
- MADE OF AIRCRAFT GRADE ALUMINUM AND ANODIZED - We start with high quality aluminum. The anodizing process hardens the surface and ensures the tool will give you a long life of service

## Questions & Answers

**Q: Is there supposed to be packaging? I just received a ziplock bag with a stickers and Allen wrenches--the fret rocker is missing entirely.**
A: Mine came in a ziplock bag with stickers. Looks like you did not receive the correct order. Contact the seller to get what you ordered and arrange a return of the Allen wrenches.

**Q: Can this be used on bass?**
A: Yes. Bought this for my partner who is a bass player and uses it to check string height, fret level. Can also use it to measure floating tremolo bridge height on a guitar

**Q: What do the numbers on the height gauge represent?  Millimeters?**
A: The numbers represent 64ths of an inch.  This is the common unit that Fender, Gibson, PRS and others use when specifying string height.  I.e. string height at the 12th fret on the Bass E = 5/64"  & Treble E =4/64"...  Those numbers change depending on the guitar. -Greg

**Q: Wher do you measure from, top of line or bottom? Top of string or bottom?**
A: Looking for clearance so I use the bottom of the string, and my digital caliper shows the bottom of the line closer to the 100ths measurement.

### ⭐⭐⭐⭐⭐ This is the one.
*by W***S on August 13, 2024*

This is a nice piece of kit. I do some fabrication work and like accurate, thoughtfully designed tools, no matter how simple the tool is. This is one of them. The action height markers are not only perfectly contrasted, they're actually milled into the plate so the paint won't ever wear off. The machining on it is insanely good. The logo is even perfectly machined into it. And yeah, it's dead accurate. Seriously nice, here. The picks, sticker, and hand-signed business card are thoughtful touches. Highly recommend.
