I'm not sure that there is a specific collection for the Real Book, but there are play-along tracks out there. Jamey Aebersold probably offers the most extensive collection.

As you will see, there are over a hundred different volumes from assorted collections of standards to specific composers/musicians, as well as specific styles of jazz - bebop, latin, etc... You can remove the bass by killing one of the speaker channels.
Also, someone just recently posted this link on TB:

This is a great site and it's free. You can't remove the bass without removing the drums because they are on the same channel. I use it from my laptop speakers, so the drums and piano come through while the bass is barely audible.
Another option is to use an actual recording and play along with it. I mean, you can be playing with Miles, Duke, Monk,... whomever you want. Again, using a speaker system that doesn't cater to the low frequencies works best for removing the bass.
Lastly, find other players that are looking to play standards. They are out there on all levels. While a play-along offers good, sometimes great, training, it is only a limited substitute for the real thing.
Best,
