hi, im still pretty new at bass, and am still developing techniques. not that slapping is the most musical thing done to a bass, but i still really wnat to learn how to do it. my main problem is that i always end up hitting multiple strings with my thumb. also, i have trouble when slap/popping, i always get a trot, never a steady rythem. i know practice is the key, but i would greatly appreciate any tips that might help me out along the way. thanx a lot.
