Playing some electric guitar I never liked that good pickups can be extremly expensive. From the engineer's point of view, I did never understand why there are only few active pickups and why not imtegrate the Amp and ADC into the guitar (also thinking of wireless transfer using TI pure path transceiver chip). And rare earth elements used in good magnets are not the best solution when it comes to emvironmental issues!
Wouldn't it be then not a nice approach to sense the strings directly ? The LDC1000 would offer enough speed and sensitivity, but the coil setup would be somehow challenging. Maybe ... I schould take a look at turntable pickups first ...
Anyway, there is a quite similar roadtest ongoing investigating a microphone based on the chip. I am following very curiously
