Pinpoint those pesky high frets, and check the final height after you've redressed or replaced them, reach for the Fret Rocker!

Our 4-in-1 mini straightedge spans three frets and "rocks" to indicate uneven fret heights. Precision-machined for accuracy to .0015" per foot, the 4", 3", 2" and 1-5/16" edges make it versatile for any fretted instrument, from basses to guitars to mandolins.

The Fret Rocker is made of 1/8" nickel-plated steel with a satin finish, for durability in professional use. It's an indispensable diagnostic tool, before and after partial refretting and recrowning jobs. It lets you do more accurate fret work for better playability.

Essential for fretting
This item is one of seven tools included in our Essential Fretting Tool Kit, a compilation of tools you'll need for the fundamentals of fret work. Kit also includes our book, Fretwork Step By Step by Erick Coleman with Dan Erlewine.

This tool is a must have for any guitar owner. It locates high frets and allows you to know which frets need to be adjusted down to eliminate buzzing.

Very nice product

Bought one of these to check my instruments over which I had never previously done. Located and identified several areas of concern. Its a great product very sturdy, the lengths are really cool. Nothing bad to say about the fret rocker, it works great!

Fret Rocker

I bought this to conquer a problem with my Ibanez RG's and S series. They all have the wizard type necks, and they all have small issues above the 12th fret with buzzing. This allowed me to find all the spots and fix them so now everything plays perfect. I am not a luthier by any means, but I am handy enough to do this.

Found my problem immediately

Nothing more to say. I had a hunch that maybe a fret or 2 were high and on receiving my Fret Rocker (which I had been putting off for too long) it exactly nailed my problem. I also found out it wasn't the whole fret, just half at the high strings on the 21st fret. Great, simple tool.

I've been around guitars for awhile. I became 100% disabled and homebound. So I started doing repairs and set-ups to keep busy. Perfect tool to put in your tool case.

Really great!

This is a very nice little tool and works well for its intended purpose. My only complaint is that even the small side is a little too big to check the high end of a mandolin or ukulele fretboard. But it is well made and I have no real complaints about it for guitars and banjos.

Necessary for any workshop and built to last.

A wonderful tool - Now what?

This is a great tool for looking for bad frets. I have four guitars, Strat, Gibson ES, an old Epiphone Genesis, and an acoustic Takamine. All of them were pretty good. My '76 Takimine had several frets that were high and low, mostly way down on the neck. Now I have to decide if I want to take the next step and dress them. I have a friend who has built many beautiful archtops, and I am probably going to go to him for some guidance. I would bring this tool if you are buying any guitar and want to know how much work it will need. It does it's job perfectly. Then you have to do the real job - repair what you uncovered.
