I had problems straight out of the box with the Tune-O-Matic bridge on a Bigsby-equipped guitar ― not only rattling but also the strings binding so badly the bridge was actually trying to rock a little with each dip of the Bigsby in spite of copious amounts of graphite powder applied to the saddles.
I replaced it with a roller bridge I had lying around and haven't looked back. The radius is off (my guitar's neck is 9.5", like the Mascis I believe?) but I hardly notice it when playing, and tremolo action is very smooth. I know some claim that roller bridges are tone killers, but I can't say I hear a difference with the TOM ― that is, apart from the lack of rattling. Then again, I don't have audiophile-grade ears.
My advice is get a cheap roller bridge off eBay. If the radius mismatch doesn't work for you, you can still get a Staytrem when they go back in stock.
EDIT: This is what my replacement roller bridge looks like.
You can get a Wilkinson branded one for about €20 or a noname copy for even cheaper. Radius is 12", be sure to check string spread and post spacing as well though. Mine dropped in perfectly, but my guitar isn't a Fender or Squier.
EDIT 2: I might be wrong, but I think the stock Adjust-O-Matic bridge on the Mascis JM has a 12" radius, so it's mismatched out of the box. If that didn't bother you before, then the Wilkinson-style roller bridge probably won't, either.
