If you are just starting out with bass, leave the effects alone. Learn to play it first, how to connect with it, how to lock in with the drummer, all the basics. Add effects later. Most bass setups are completely dry anyway. If you want to add anything, toss an overdrive like a Boss SD-1 or Ibanez TS9 out front for a little grit. Not a lot, just a little. Compression is helpful too but not necessary when starting out. It can actually hamper you from learning control of the bass and how dynamics react so leave that out for now. Walk, don't run.
