Leo Fender came up with some very innovative ideas. He first designed, and then improved upon, many electric guitar designs, pick up systems, and related parts. However, with the passing of time, new ideas pop up from time to time, and then things just change. Take for example guitar tremolos.
Leo Fender had some great tremolo ideas in his time. My personal favorite design is the string thru body, but that is not the only tremolo idea that Leo had. In my opinion, the single most important idea that he came up with is the tremolo and the tremolo bar. He came up with the idea of using a tremolo bar in order to create those diving sounds. The design has been used for decades and decades, but time has shown that it has some flaws.
To begin, with the tremolo bar, came some minor tuning issues. You see, each time that the string tension changes, the tuning is altered. To remedy that problem, folks have added tilted head stocks, added “string trees”, re-designed bridge parts and pieces, added springs to the rear of the tremolos, and on and on. The radical idea of completely locking the strings “in tune” came along (via the locking nut and the floating tremolo), and that seemed like the final answer. But, even that idea seems to be tweaked every few years or so.
So, lets take a look at some of the newest tremolo designs. Several new tremolo designs come to mind, and they each solve different problems, and use different approaches in order to reach the “stay in tune” dream.

There is not much to be found on line about these little gems. Here is a Youtube page about guitars with them installed.
