Mastery bridge issue...height screw slipping

Post by romo » Sat Oct 23, 2021 10:54 am

The treble side post on my mastery bridge keeps slipping lower and lower. I will be playing and notice the high E and B strings fretting out on bends, then see that the hight of the bridge on that side has slipped really low. It's an older bridge I purchased from Mastery about 11 or 12 years ago. I have had a newer Mastery on a different guitar for the past year with no issue. The guitar is a Squier Classic Vibe. I'm not using Mastery thimbles but the posts fit really tight into the stock hardware. Is there anything I can do to tighten up that height adjustment?

Blue Loctite, formula #242. It's basically glue made specifically for screw threads, and can be broken with the torque provided by hand tools. Just don't buy the red, you'll have a bad time.

Thank you! I'll give it a try.

I just found this thread as I have the same issue on both bridge posts. Over time the action drops enough that strings are choking out from about the 12th fret upwards, even without bending. I made accurate measurements of the height of the bridge plate above the pickguard, and the heights of the saddle tops above the bridge plate. I measured again after a couple of gigs - no change in the saddles, but both posts had dropped about 0.5mm.

So next time I change the strings I will apply some Blue Loctite. Trouble is I use Elixirs, and they last a very long time!

Just put a capo on the first fret, loosen the strings and pop the bridge out that way man. Means the strings can be easily kept on. The odd time I have to adjust the truss rod say, that’s what I do. I use Thomastik Infeld’s, so rarely change strings either.

Worth checking first that both of the required adjustments to the height posts have been correctly made, one with the medium allen wrench (5/64"), and one with the small allen wrench (0.050").
