So, I've been playing bass for a couple of years now and am finally starting to feel pretty comfortable with my fingerstyle playing, so it seemed like a good time to try to learn how to slap. I've watched a few videos online and tried to integrate it into my normal practice. Whenever I do try to slap, though, the strings rebound off the pickup end of the fretboard, immediately muting them and causing a pretty annoying rattle. Is this a matter of technique, string gauge (my strings are pretty light...E is a .096), action (haven't measured it, but I don't think it's particularly low or particularly high), or what? I don't seem to be able to figure it out on my own.
