Fair comment. I was just offering an alternative idea of what might be wrong but I agree that it makes sense to start with the basics.
For the bridge wire problem, on my LP I (very carefully) pushed the wire down with a small screwdriver, putting a small kink in the wire in-between the saddle adjustment screws and that fixed it. Another solution I've read of is to use a dab of clear nail polish to temporarily fix the wire into place.
On my Casino, I was getting sick of buzzing so I had a Gotoh wireless ABR installed.
