Any bass will work as long as it has a good set up.
On a bass it takes some good finger strength. If you're just starting out and the finger strength isn't quite there yet you can use two fingers. If you're tapping with your index finger, you can place your middle finger behind your index finger to help support it. It's almost like the pad of your middle finger is on the nail of your index. Ok not quite but that kind of vibe. Once you build up your strength you wont need to use this technique, but it comes in handy if it's been a long gig and you're getting tired.
Truth be told, I started with guitar during the height of the 80's shredder era so two handed tapping is second nature to me so I guess I'm cheating a bit.
