Something has just occurred to me and I want to say it out loud(er... type it so other people and read it), and tell me if I'm mistaken or what: Piezo pickups are the future. So that may be an overstatement, but here's my thinking. Neck pickups, bridge pickups, musicman "sweetspot", P-bass, J-bass. These all have characteristics bases primarily(although I realize not entirely) on the location of the pickup along the length of the string and that locations relation to node points. And they all have "compromises". As you fret different notes, the node points change and the pickups are going to reflect that sound differently. So... where do all of these node points intersect for every note? At the bridge(not the nut because the note may be fretted). So a Piezo pickup would pick up every fundamental and n-ary harmonic frequency of every fretted and open note. That would give you a more even tone and more flexibility. It would be possible w/ pretty inexpensive electronics to filter this in any way the player prefers. I assume this is why things like the Variax primarily use the piezo pickups, they add more extensive DSP to obtain even different instrument sounds, not just variations in bass tone. So, why isn't this more popular? I would think that Piezo w/ some quality low-pass/high-pass filters would be the answer many people are looking for. Am I crazy?
