Music Nomad MN822 Precision Fret Rocker

Ultra-precise Fret Rocker and Comprehensive Action Gauge

Quickly diagnose uneven frets, action height, and pickup height with the multi-purpose MN822 Precision Fret Rocker from MusicNomad! This stainless-steel 0.07-inch rocker boasts five ultra-flat sides with four straightedge lengths, enabling the Precision Fret Rocker to perfectly span 3-fret increments anywhere on the fingerboard. How does it work? By laying the Precision Fret Rocker across any three frets, you can easily check to see if the middle of the three frets is high, as a proud middle fret will lift the center of the rocker up like a seesaw, rocking up and down onto the first and third frets of the span. Moreover, the MN822 also sports a wealth of valuable information and measuring rules printed on both sides, including fraction/decimal/millimeter conversions, recommended measurements, an action gauge, and a pickup height gauge. Whether you’re performing occasional personal setups or running a full-scale repair shop, MusicNomad’s MN822 Precision Fret Rocker is a must-have addition to any tech’s toolbox.

Four precision-ground straightedges

The MusicNomad MN822 Precision Fret Rocker features a unique 5-sided construction, with four different lengths to perfectly span three frets anywhere on the fingerboard. Each side is ground to an incredibly precise tolerance of +/-.0015”/ft for the utmost accuracy, while the rocker’s heavy-duty stainless-steel build clocks in at a robust 0.07 inches for a high-quality weighted feel. Finally, while the MN822 Precision Fret Rocker is built to last the long haul, City Music’s luthiers recommend rigging it up via the convenient hang hole when not in use.

A comprehensive measurement tool

So, you’ve rocked your frets, everything checks out, yet you’re still getting fret buzz. Don’t worry — it’s a common problem, which usually means another setup-related issue. Luckily, the MN822 Precision Fret Rocker sports all the setup specs you could ever need, printed right onto the side of the rocker itself! From common action heights to fraction/decimal conversions to multiple action gauges, the MN822 Precision Fret Rocker packs the power of an entire instrument measurement arsenal into a single do-it-all tool.
