Question:

"Markok asked "Hi: I am trying to learn the RHCP song "Can't Stop". I have the main riff down ok picking the strings individually, but I would like to learn how to mute the other strings to get that nice percussive, chucking effect. Any guidance/tips you can provide are much appreciated! Thx in advance...""
