buzzing at bridge

[ElliotBass]

Hey, on my fender mexi p bass, still using stock bridge, theres a buzzing or rattling at the bridge when i play A, D and G strings.

Is there something i can do to fix this? or is it easier to get new bridge all together, Thanks a lot

I've had the same problem with my MIM. If it's what I think it is then the spring on one of your saddles isn't long enough and doesn't push against the saddle.
Best fix is to find a better spring, stretching the spring you've got might work. You could always jam some foam or something next to the affected string too, just watch to make sure it doesn't affect tone. By itself it's not enough of a reason to replace the bridge, but if you've got the dough a denser bridge will improve the sound of the MIMs.
