I'm ok but not great at finger picking I tarted learning stop this train by John Mayer and the I've got the fingerpicking down in the main riff, I haven't even really tried it with the slap on this bass stings yet. Should I learn the rest and try and add this after I learn all the picking. Patterns and chord changes or should I get it over with now? Also I use three fingers and my thumb and I saw a live video of him just using his thumb and index finger, does that make a big difference with the slap? I'm looking at spending a good amount of time learning this song because it's a song I'd like to have in my repertoire without any 'fake' parts so id just like to hear anyone's opinion who's played this song
