If I want to improve my bass guitars tone by replacing the bridge and I have an Accu-Cast B20 bridge, what bridges would you recommend that would fit more or less right into the spot where the existing bridge was.

If it would work, id like to put a BadAss II on, but would that work on an Ibanez SR500?
It's going to be hard to put a badass on a archtop like the Ibanez SR, the badasses are made for Fenders and flat top basses.

But I have seen some badass bridges on Warwicks before so I suppose it could work, but again, it's going to be pretty hard.
