Hey all, a while back I realized double thumb was too difficult to incorporate into my style of slapping. I play with the the thumb slightly pointing downwards, which makes "upstrokes" nigh impossible. So, I started playing with what I can only describe as double strokes, i.e., my thumb slaps the string twice very rapidly. (hit,rebound,hit,pause). I've also managed to squeeze a pluck on the same string in between slaps, enabling me to get fast percussive single string lines, (slap,slap,pluck,..). Just curious if anyone else has learned this instead of/in addition to the "proper" double thumb technique?
