1980 'Gibson Pickups & Parts' brochure, page 10: 3-point Tune-O-Matic bridge
The new Gibson 3-Point Tune-O-Matic Bridge is not just a bridge. Its a threeway overpass. Because you not only have individual string control, you actually choose the bridge location. Underneath are three positioning holes on each side for nine position possibilities. The design is so revolutionary, we've applied for a patent. In chrome or gold. The Gibson 3-Point Tune-O-Matic Bridge. Now your strong point is three points.
In February 1981 the 3-Point Tune-O-Matic bridge had a list price of $31.95 (chrome) or $40.95 (gold).
