I rarely go all dive bombs and whammy crazy on mine because I haven’t figured out quite how to incorporate it into my playing but I’m always surprised at how well mine stays in tune when I do bust out the VH dive bomb shenanigans. It’s not often that I do that but I did a little Beatles birthday video for a buddies 50th and finished it with a little solo and dive bomb into an E7(#9) Hendrix chord to finish it off. I had to do it several times (because I screwed up the playing, the timing or the singing numerous times) but the guitar stayed in tune throughout. AND that’s with vintage split tuners, a bone nut, 6 screw Trem and an American Standard string tree. That it would return to pitch after being completely slackened and then returned is mind boggling without locking tuners and a roller nut but it does it. Most of the time I just give it a little wiggle to make the notes shimmer and it never goes out of tune.
