sagging saddle

[Bob Faulkner]

Hey Ken.. The saddle for my G-string on my BSR4EG has developed a little bit of an issue and I wanted to ask your opinion on how to fix it. The saddle has started to "sink" over time in that every 6 months or so I have to break out the allen wrench and raise it back up. Once I set it's height where I want it, it will slowly work it's way back down to the point were, if I don't correct it, the saddle will start rattling against the bridge plate. It's not tragic or anything as adjusting the saddles every 6 months isn't too painful, but I'd really like it to just stay put when I set it.

It made it to about 5 years old before it really started doing this. It was fairly low already, and only noticed it when it began rattling. I have reset it 2 times now and it's again in need.

Any ideas on how to "tighten" the screw posts on the saddle so they don't drift under load?

Thanks!
