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.
