The Dynamic Vibrato is often confused with the Fender floating tremolo, which it resembles. The original production runs of the two overlap by more than a decade, but the mechanisms are quite different. The existence of a few 1960s Mustangs factory fitted with the floating tremolo has probably added to the confusion. The concealed mechanism is in a chamber of a completely different shape and position, requiring an impractical amount of woodwork to convert from one to the other, and the mounting plate is of a different shape with different mounting holes.
