Top Deflection Gauge

The Top Deflection Gauge simplifies neck resets and bridge work on guitars and banjos. It precisely measures soundboard deflection when a guitar is unstrung. This helps avoid trial - and - error in neck resets (by restoring bridge height) and in bridge work (contouring new bridges and routing saddle slots accurately). For banjos, it indicates head deflection for optimal sound. With an aluminum beam having holes for different soundboard widths, a swiveling foot, and a highly accurate dial indicator, the 14" x 1" x 1/2" gauge streamlines crucial instrument adjustments.
