The groove needs to be modified so that the saddle sits nice and snug, and vertically correct.
That's where your McGuyver skills come into play. But because this isn't exactly a rare problem, you'll most likely find specifics on repairing the saddle groove, on trusty old Google. It might involve making some shims to fill the widened space, and you might have to produce from the depths of your Garage; some sand paper, thin blocks of wood or plastic, cutting utensil, and no less than a 6 pack of beer.

And, by all means, do not glue the saddle into the slot.. Whatever you do for repairing your saddle should be reversible in case you need to edit/undo if you know what I mean.

Good luck.

Gotcha! Thanks for the info. I guess I'll get on it and try to find something I can jam in there.

can't answer the why but that's definitely how my acoustic is put together. i have a half dozen pegs that hold the ball of the string in a hole in the bridge that then get pulled over a chunk of bone, but aside from those pegs everything is glued to the body.

^ That sucks.

If you had to replace it, of course.

indeed. it's a bridge i'll cross when i get to it OOOOOooooooooooohhhh!!!! hahahaha

LMAO.
Specialty jokes never get old.

I just wanted to stop by to say how impressed I am with all of the knowledge present in this community.
