Yamaha still remained an innovator during this period, however. The company already had more than two decades of experience building guitars, and the decision was made to pursue these new opportunities in a grand fashion. The SG and SG, which featured a single-cutaway, dual-humbucker, set-neck design similar to a Les Paul, were the first Yamaha electric models to officially arrive on American shores in Yamaha has even refined its own complex neck-to-body joint for acoustic guitars that provides an enhanced level of contact between the neck and body.
Also inYamaha Guitar Group, Inc. Ampeg has produced some of the music industry's most innovative amplification products, including the first bass combo amp, the first guitar amp with reverb, and the de facto stage bass amp, the SVT.
These guitars still have a strong cult following in Japan today.
John Denver ordered two custom L guitars featuring Hokkaido spruce tops and Brazilian rosewood back and sides inwhich he played in concert and television appearances during the late Seventies.
At the same time during the mid Sixties, Yamaha expanded its production by offering its first steel-string and electric models, including bass guitars.
By the mid Sixties, the entire world had a fever called Beatlemania, and the only prescription was more guitars. For example, the Weddington Custom featured a single-cutaway mahogany body with figured maple top, two humbuckers and Tune-o-matic bridge with stop tailpiece, while the Weddington Special had an all-mahogany body with single-coil Pstyle pickups and adjustable single-piece bridge.
In recent years, Yamaha has also revived some of its past glories, albeit with modern enhancements, improvements and updates. The most innovative feature was its hexaphonic piezo pickup that provided a separate pickup for each string.
