Watch the Tapping online guitar lesson by Dmitry Lisenko from Percussive Acoustic Bass (Foundry)
I would say that tapping is the most important topic on to your way to playing percussive acoustic bass. We're not talking about super fast solo tapping licks, it's mainly left hand tapping. Speaking about the right hand, it's a bit harder to tap notes on acoustic bass than on electric because of the higher action and string tension. But with time, you will get used to it. Right now you have to learn to play everything you did with both hands, only with one left hand.
The best way to start is to play scales, or any riffs you already know with just your left hand. Pay attention to the muting. It's very important - because of the hits, bass is constantly shaking therefore making the open strings vibrate. Remember, the left hand is playing the bass part (or melody), and the right hand is playing rhythm. You have to think about them as a two different instruments.
