tips guys..i need em!! -what do you concentrate on when making your own bass line for a song?? (composing one, if you will ) -What part of the thumb do you guys use to slap accruately? thats hard for me to slap accurately on the A and D strings, without making other buzz's on E and G, is it just repetition creates perfection? or do you use effects like fuzz so the unwanted noises go unnoticed? THANKS!!!
