Tight bass can be created by a bass player damping every note, and
utilizing over-damped drums. Listen to this sort of thing outside with
no acoustic boundaries and there ya go!
I've been playing bass since 6th grade. True- it gets a lot more percussive played that way. But impact is one thing- tight bass is another. If the bass is right, its got impact **and** definition. If its tight bass, its got punch but the impact is insufficient and no definition- you keep trying to turn it up to get it to satisfy. Now I might be harder to satisfy because I've played bass so long; in my band right now I play keyboards and keys are more capable of making unnatural bass notes, but even there, the sound is usually a combination of what the player hears in tandem with whatever speaker he uses to play the keys with. But if I'm playing in a club, even when playing such bass, its anything but 'tight'. The speakers are interacting with the room...
