SM5046 StewMac archtop bridge fitting jig

Get a better fit for better sound! This is the easiest way to sand your instrument's arch into the bridge bottom. For guitars and mandolins. The jig holds the bridge base while the bridge feet are sanded to match the instrument's top curvature.

Proper contact of the bridge feet is critical to the sound of an archtop instrument. Rubbing the bridge base over sandpaper on the arched top of the instrument is a standard technique for matching the bridge and top surfaces. Unfortunately, because it's difficult to hold the bridge by hand and keep it correctly aligned, the bridge feet are usually sanded unevenly into an ill-fitting contour. The instrument loses tone.

This aluminum jig attaches to the bridge base with the bridge's own thumbweels. Lock the height of the jig roller for the desired bridge angle and move the assembly over the sandpaper. The 3-point contact assures you the bridge feet will be correctly contoured. No more lost tone!
