What are the thoughts of using the right hand thumb occasionally in non-slapping parts? I tend to do that sometimes when a note is supposed to let ring. For example in the beginning of Sweet Emotion, I play the A string with my thumb, instead of playing it with my index/middle finger. This way I can let the A string ring, which is useful when you don't have a keyboard etc. and need to have a fuller sound. Obviously the same effect can be achieved by not letting your index/middle finger mute the A string after playing a note on the D. But my justification is that if I were to play with a pick, I wouldn't need to worry about that and playing with your thumb essentially mimics that. (Beginning of My Friend of Misery by Metallica is another example, and the original part was recorded with a pick player). Anyone else does the same or do you guys think that right hand thumb should never be used in that manner? I never considered this to be a problem for me but it looks/feels like fingerpicking on a guitar and for some reason I suspect that that's a non-bass way of playing, whatever that means
