A playback stylus assembly for a phonograph record stamper and matrix is provided. The stylus assembly comprises a pair of conventional jeweled styli members each terminating at a tipped end. The styli are bonded to each other but offset from one another to form a 'V' to ride along the stamper ridges. The ends of the styli opposite the tip ends are bonded to a tube.
