ok, maybe that sounds nuts.....but I'm trying to get serious about learning slap, I've noticed this a little while I play, but from in front of the bass it's REALLY noticeable. Sometimes the satisfying "tick" sounds more like a WHACK. It sounds great if I'm 5 or 6 semitones up the fingerboard, but open strings, or the E or A strings 2 or 3 semitones up from the nut gives more of an ugly "whack" sound. I've experimented with dampening the fingerboard (stuffing a rolled towel between it and the body), and that seems to be an improvement. Is that a bad idea? or is there some "proper" way to accomplish the same thing? or another way to address the situation? or is it all down to technique? Thanks in advance.
