The PRL-8721 Ratio Tuned Machine Heads are the first and only machine head to incorporate the different string gauges into the tuning equation. The gear ratios range from 12:1 to 39:1, specific to the relative core size of the string being spun on each, resulting in a consistent response across all strings. One half turn is a semi-tone; one turn is a tone.
Installation is unprecedentedly simple, as each set of Ratios comes with four full sets of Invisomatch mounting plates. In most cases, whatever the current hole profile under the old tuners - one or two screws, 45 degree, 90 degree, etc - one need only position the appropriate plate between the tuner and headstock, utilizing the existing screw holes with no drilling or filling required.
The PRL-8721-C0 is a set of Ratio Locking Tuned Machine Heads for an electric guitar that uses six in line tuners. It has a contemporary mini shaped button, has a two pin casing and is finished in chrome or gold.
Includes InvisoMatch Standard Mounting Plates for easy installation. Fits most headstocks.

What started as a simple string and pedal sales catalog has grown exponentially over the past thirty years. The early days were a time where catalogs didn't have much of a presence in the industry, but what began as a college dorm room operation grew rapidly. In 1986 we moved to a full product offering and 64-page catalog, which over the years has grown to 162 pages. Join the AMS family and get your free catalog now!
