Does anyone make a locking strap button that fits a neck plate screw? If not, how to people who use a neck plate mounted strap button do it? Do you drill another hole into the plate/neck?
For context, my purpose isn’t necessarily to solve “neck dive.” I want to change the fulcrum point to make the bass hang more vertically.
Thanks
You would need to drill a hole in the plate that fits the max diameter of the screw.
However, do not to drill the hole while the plate is mounted to the neck or the resulting hole will be too large in the neck wood.
If this seems a bit confusing, consider practicing with some scrap wood before tearing into your axe.
Remove the plate; drill the plate hole with the larger bit first that accommodates the max screw diameter; then tape the plate in place on your neck and make a small mark through the dead center of that hole. Then carefully drill a hole in the neck with a smaller diameter bit so the strap button screw will fit snugly when screwed in.
It’s not difficult, but things need to be precisely done. If you don’t feel comfortable doing it yourself, take your instrument to a qualified tech. It’ll be a piece of cake for him/her.
That’s pretty extreme-ish for bass. But of course, it’s been done, lol.
Hadrien Feraud often plays with his strap button like that, but he likes to hold his bass high. The upper frets are where he solos and, boy, does he ever solo.
This is position of the upper strap button on the Steinberger XT-2…
Having the strap button in this location effectively throws the bass neck to the left, ie the nut is probably 10cm to the left of where it would be if the button were located on a normal horn. Many Steinberger owners, me included, spend hours dreaming up mods to get the bass into a more standard position.
Before attacking your bass with a drill, might be with hunting out an XT-2 (they’ve freakin’ cool basses as well 
)
If want to maintain a classical seated position when standing without having to use my hand to support the neck. How do I accomplish this?
I would suggest the standing photos you have posted are not a classical position. Compare the position of the horn relative to the shoulder they are much lower than the ‘classical’ position. I aim for the same but have my bass quite a bit higher so sitting or standing it is in almost exactly the same position.
I should add that I have no neck dive problem with my Ibanez but it is a medium scale so a little less top heavy. My medium scale acoustic does have major neck dive (lighter body I guess) but if use a nice grippy strap that almost elliminates it (although I mostly play that one sat down).
Hadrien is obviously seated in this pic, but he has his strap button mounted on/close to the neck plate.
He prefers his bass high on his body, seated or standing.
My concern is the angle of the neck.
Yep, it sure is purdy.
That pic is from years ago, before Hadrien was a die-hard Mayones player.
