This is really an essential requirement for perfect intonation. Heavy brass with chrome plating! Leo Fender himself would approve wholeheartedly. He admitted that his development continued throughout the design of different models. At the time of the first Telecaster he had apparently not cottoned on to the importance of individual string adjustment. There are many factors that combine to produce the classic sound - Pickups, neck, bridge, etc. and each of us has an idea of what is more important. It was way back when string sets came with a wound G, (which was almost always the first to break), so I have no hesitation in changing to this. I still think about 96% of the sound is entirely down to the pickup. If not, I can always change back.
