You meant to say an automatic way to throw the guitar out of tune.
There's a reason Bigsby is nothing but an antique novelty.
Tailpiece/bridges need to be as solid as possible to 1-keep the guitar in tune, and 2-add sustain.
Acoustics get bone bridge saddle and nut, electrics get solid brass bridge and tailpiece, the heavier the better.
Been playing 50+ years and I have owned a Bigsby in the past....have a small clue about this shit.
