Re: Determining factors that cause a bass to have a good "slap and pop" sound.
To the OP: Here's my take on it.
I agree with One Bad Monkey: you need to develop hand strength and dexterity. Some of the best bassists I've seen could crack a bowling ball like a walnut.
The slap technique, as developed for electric bass, has been used mostly on solid body instruments (usually variations on the Leo Fender designs for Fender, Music Man and G&L).
For many people (myself included), the Jazz bass was the standard. Larry Graham was an early advocate of slap, and the Jazz was his choice.
It has advantages over the Precision, mostly the neck profile and the more detailed sound of the single-coil pickups.
Leo Fender branched off at that point for Music Man and G&L, creating active electronics and dual-coil double pickup variations on the Jazz design, which still maintained the same basic J sound.
A bit of mid-frequency "scoop" (which has the effect of boosting the lows and highs) emphasizes the percussive element, and reinforces the fundamental tone.
On a big stage, though, it tends to overpower other instruments, so I use that EQ profile sparingly.
Hofner tries to emulate a more 'acoustic' sound for its' signature, IMO. I haven't seen it used as a funk machine.
However, there are various techniques for slapping acoustic bass, which give an equally percussive sound.
Of course, a lot of energy is expended getting the sound to project on an acoustic instrument... quite the aerobic workout.
Here's an example...
Yes, set-up makes a difference. I've found my best results come from having the action in a sweet spot, neither too low (causes excessive buzz) nor too high (too difficult to fret).
A lot of slap bassists also alternate slap with a hammer-on technique to get more complex rhythms -- guys like Marcus Miller and Victor Wooten -- so having a quicker action helps there.
Strings? Most slap players will go for the brighter-sounding round windings (steel), to get real ringing, piano-like overtones.
Experiment, practice, and try different things. Being different leads to being distinctive.
