I'm wondering if we musicians playing stringed instruments in the future will be playing metallic based strings. Of course we are dependent upon them now with our antiquated electromagnetic field pickup technology. But, are metals the best for an electronic-analog signal chain? There is or will soon be a material that is superior to steel or nickel or whatever at reproducing frequencies that please the human ear. Will we develop new pickup technology? Maybe the string is able to emit a magnetic field onto a non magnetized coil? Maybe a nano-tech carbon fiber string can hook up to an optical pickup? I know we have piezo but that didn't really cut it or we would all be using them. The future brings digital but I think that there will always be a demand for analog in the music world - just look at how many still insist on tube technology when solid state is "superior" on paper in every way. Just wondering...what will the future bring? (my dream is a "force field" that lets you feel strings that aren't really there - with an all analog signal path). What do you think?
