Bridge woes....

[millsbass5]

My main 4 string bass is an original '75 Jazz Bass.Well,it's all original except for the bridge.The original bridge was replaced(Badass, by me) back in '90-'91.When I purchased the bass for $350.00,the only issue was the bridge.The saddles are rusted INTO the saddle-height screws or,vice-versa.I've tried the ol' Rust-oleum,WD-40,to no avail.It's rusted so badly,that the slots where the screwdriver tip fits is rusted away completely.Any ideas?Remember,this bass gets played out in clubs on a weekly basis.I guess I could find an original bridge for it.I would just like to have the peace of mind knowing I have an all-original '75 J-Bass.I also have a '71 J-Bass w/a Badass,too.I'm betting that's why it has an aftermarket bridge.IS THIS A COMMON PROBLEM WITH THE BASSES OF THIS ERA??

Take the saddles off, vicegrip onto the 'bottom' of the height setscrews, unscrew them that way, gently re-tap the saddles, replace the setscrews.

Thoughts?

Let the whole assembly soak in wd-40 for a couple of days. Get the screws out thru the bottom as the other poster mentioned, then repair / replace the set screws.

Loosening rusted bolts requires the use of a penetrating oil like 3 in 1. The chemicals of choice for dissolving rust are CLR and Limeaway. They have a similar active ingredient as Naval Jelly. Use the penetrating oil to free up the adjustment screws. If they can be salvaged put them in some Limeaway with the saddles. Rinse very well with clear water and dry with a hair dryer immediately. If you neglect this step you will see a light coat of rust within an hour.

Sometimes, when nothing else works, try soaking the entire bridge in Limeaway and it will free everything.

WD 40 is not a penetrating oil, nor is it a lubricant. It will not eliminate rust. It is a poor lubricant. The WD stands for Water Displacement. It is designed to protect metal surfaces against rust.

N.B. CLR and Limeaway are dangerous chemicals. They will burn you. The fumes are probably not very good for you either. Take safety precautions. When working with them wear goggles and gloves.
