Crimson's new and improved steel Fret Rocker, now with 5 precision ground straight edges, is the first rocker to work on Guitars, Bass Guitars, and Mandolins, (and other short-scale instruments).

A fret rocker is an ideal tool to pinpoint that elusive high fret that has been giving you trouble and causing your guitar to buzz.  The five sides are precision cut from 3mm steel and then HAND ground and lapped to a flatness of 0.001mm in a meter. This is flatter than most commercial straight edges and guaranteed with the Crimson Guitars seal of quality and durability.

Painted with a hard-wearing, tactile black matte finish, which makes it much easier to see any gaps when you are using this tool and reduces the risk of dropping it on the instrument.

Each side of the five-sided straight edge is a different length and fits neatly over 3 of the frets of the instrument.  If it rocks then the middle fret is high and needs to be dressed using our fret levelling or spot levelling files.
