Fretbar understring leveler, 11,5 cm length

Now, you can level your frets…with the strings ON! Matt Brewster from 30th Street Guitars brought us this amazingly simple (but effective) idea for getting perfect fret dresses with the strings still on the guitar. This great idea became the StewMac Fretbar® understring leveler. This revolutionary new tool lets you level your frets under full tension without removing the strings. It’s designed to work with 2,5 cm wide 3M Stikit Gold abrasives for ultra-fast set up and leveling.

Fret work without guesswork
With the Fretbar you’ll level the frets with the exact tension the neck has when played. This is because the Fretbar fits UNDER and BETWEEN the strings, with the guitar tuned to pitch. The precision-ground surface is just 2 mm thick, allowing you to glide under the strings when leveling. Because the neck is under tension, you’ll clearly see every hump, twist, high or low spot. With the Fretbar you can level the frets without worry or any “surprises” that pop up after the job.

There is a Fretbar for every leveling job:
• 11,5 cm length ideal for spot leveling problematic frets all over the neck. It’s also perfect for creating fallaway on acoustic guitars.
• 23 cm length is designed for smaller necks like ukuleles and mandolins. It also works for leveling full scale necks and spot leveling.
• 46 cm length makes it easy to level an entire neck. You’ll quickly and evenly level most of the frets at the same time, without the added danger of running into the nut, saddle, or hardware.

A string jack to use with the Fretbar is included. Put the jack in front of the nut to raise the strings without changing the tension on the neck.

Works with the strings off too
This is also a great all around fret leveling tool. Used with the strings on or off, the precision-ground surface works quickly and accurately to get frets level. If you’re just getting started or have a ton of experience, the Fretbar is a great option for any fret work.

Built for a lifetime of use:
• Made of durable extruded 6061 aluminum
• Guaranteed accuracy of ±0.0015″ per foot
• Designed to work with 2,5 cm wide 3M Stikit Gold abrasives
• Works with the strings on or off
• Your fastest and most profitable leveling ever
• Because you don’t need to remove or replace the strings, you’ll save time on every leveling job.

Each Fretbar is 3/4″ (19mm) wide x 1-15/32″ (37mm) tall extruded aluminum, and available in three lengths: 4.5″ (114mm), 9″ (228mm), and 18″ (457mm).

Works on stainless frets, too!
All of our tools are suitable for use on stainless-steel fretwire. Modern stainless-steel fretwire is known to be harder than the traditional nickel-silver blends, but our own shop experience indicates the wire does not cause premature wear of files or sandpapers.
