The totally new True Track™ tape guide system built into every Ampex GrandMaster™ cassette shell represents the state-of-the art in jam-proof
engineering. Specially calibrated fore and aft guides minimize vertical tape travel which results in superior azimuth alignment for the ultimate
in sound reproduction. This feature also ensures exact tape-to-head registration from side 1 to side 2. In addition, the critically important friction plates are manufactured from graphite-impregnated Teflon polymer, the very best material available for even tape packing and ultra-smooth operation.
