Dear SongJinYoung.
I'm Keiichi Miyamoto from Japan.
At first, I think your English is very very better than mine. (**)
Regarding Slap sound, I have just talking about this in Talk Bass Forum.

And my sound sample is;

How do you think about it?
I think the PU balance between Front and Rear gives hints me to obtain better (I mean generic or popular(FenderLike?)) slap sound with Ken Smith Bass.
;==
My Ken Smith BSR6TNE is, Black Tiger Elite 6 strings.
Crotch Walnut Top&Back with Tiger Maple core.
5pc Thru Neck with Ebony Fingereboard.
Recorded with;
Onboard EQ is All flat.
PU Balancer is on its center detent position.
PU Para/Seri select sw is both parallel.
Just one thing.
I set the rear PU height a little bit lower than default.
So, front PU sound is bigger than rear's even if the balancer is positioned center.
This setting gives me fatter sound, growl thumb and puncy pull.
It's just the example.
