Im currently trying to learn can't stop by the red hot chili peppers and i can play it fine picking individual strings but i want to play it the real way where u hit every string every time like frusciante does. Ive been trying for a really long time now and i keep practicing it but i cant get the left hand muting down so i end up with buzzing strings all the time, ive been trying to improve in funk style guitar like this for a while and any help would be appreaciated.
