An essential tool for installing any phono cartridge. Obtaining correct overhang length and alignment is essential to obtaining proper audio reproduction, and avoiding unnecessary record and stylus damage. This is a precision job and cannot be done by eye alone.

Based on long-accepted alignment geometry, but superbly executed, this alignment tool has a combination of features not available anywhere else. It is also the easiest to use.

The mirrored surface makes all measurements easier and more accurate. The mirror's parallax effect allows the elimination of sighting errors, and provides better lighting, critical in making fine adjustments on small parts. The two null points on the alignment tool are surrounded by concentric squares instead of a grid, so that the user will be measuring the cartridge body's lineup against parallel lines at each edge.

Finally, the horizontal sight-line, which is to be pointed at the pivot point of the tonearm when measuring alignment in the outer grid, ensures correct overhang length on any tonearm, irrespective of its effective length. There is an inverse relationship between the effective length of the tonearm and the optimal offset angle of the headshell.

Regardless of effective length, the two "null points," at which the stylus should be perfectly tangent to the groove, are the same. A properly designed and mounted tonearm will allow the cartridge to line up properly in both grids.
