About This Item

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 stainless steel with a durable finish for 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 1 of the 7 tools included in our Essential Fretting Tool Set, a compilation of tools you'll need for the fundamentals of fret work. The set also includes our book, Fret Work Step-By-Step by Erick Coleman with Dan Erlewine.

Rock your frets

(Customer's Reviews)

No guitar tech-shop should live without it. Makes deciding weather to go for a simple set-up or a fret dress, before the customer leaves the premises. Makes spotting high frets & doing -on the spot- repair, easy, while the customer waits.

Like another review I thought this might be overkill but the 3 sides make a huge difference on my basses. It was so fast finding those slightly high frets and so fast checking progress as they are filed. Worth every penny!


Fret Rocker is Rock'n Me!

(Customer's Reviews)

I wasn't quite sure why the price was a little high for a straight edge until it arrived and I tried it out. Then I realized the time and maybe even money spent on a fret re-leveling job. As you start at the 1st fret you will need the longer straight edge section, then you gradually shift to the smaller then finally to the smallest for the highest frets. You're always able to contact 3 frets at a time, which you must have to check for one that is higher (or lower) than the adjacent ones. Now I wouldn't DARE take a long file or sanding block and file down all of the frets to get them the same height, even when you've set your relief at zero. With that approach, you MUST have your fretboard absolutely flat, and some fretboard-truss bars won't adjust the fretboard to that perfect starting point. Taylor guitars have that NT neck which allows a perfectly flat board (if you desire it), but most all the others it's a compromise since most of them have a non-movable neck past the join at the top bout. The fine adjustments for a conservative approach to correcting one or two higher frets requires just such a tool as the Fret Rocker. It's quite thick, so it's not going to bend while you're using it. Exactly what I'd expect from Dan and the S-M crew. Excellent! And don't forget to pick up one of S-M's leveler that fits right onto the fretboard while you keep the strings on. That's the other cousin to this rocker. Buy 'em both.
