The Panorama™ Tremolo system with pop-in tremolo arm dramatically increases the range of vibrato available, allowing for deep, Strat-style dives, in addition to classic offset trem warble. Developed for the American Professional II Jazzmaster, this tremolo system will retrofit into most of the Jazzmaster and Jaguar models that Fender has created over the decades. Pair it with the American Pro Jazzmaster/Jaguar bridge assembly for the ultimate upgrade to your favorite Jazzmaster.
