In theory, you could measure the fundamental resonant frequency of the guitar mass and then add or subtract weight (lead bullets like a cub scout pine wood derby or something) to move the resonant frequency to match perfectly or harmonize with the most frequented Key or natural open tuning you use when strumming. In this way you could get some crazy big sustain and perhaps intense vibrational movement over the coils to make some intense sounds.
or you could make the guitar a perfectly irrational frequency to get perfect separation or isolation, or do some weird tuned phase canceling
Thinks Tesla earthquake machine. :lmao:
