1) Gold hardware!!! - No! Gold is a horrible colour and the last place it should be is on a guitar
2) Goldtop - Mostly a guitar thing but it's the most sickly thing ever
3) Pearloid - Unless it's on a Royal blue jazz with a maple neck
4) No head - I'd like to note hate them but it feels like my hands gonna fall off the end, bassist who played live with public enemy used one though and it was awesome for them.
5) Bright pickups - I like a bit of depth personally
6) Really "modern" look, I'm not against making basses better but there are some really ugly Ibanezes and such about
7) Light basses, although I like to jump around as much as possible it needs the weight for it to feel like a solid instrument I can rock the $%^& out of
8) Slimness - Don't like small bodies or neck or anything, for the same kinda reasons as the above, I like basses I play to be really solid so I can get a good solid tone, plus I drop stuff alot...
9) Over 5-6 strings if you don't play solo stuff, again your supposed to be playing bass
10) for then 20-22 frets - It's called a bass for a reason, unless you play solo/very chordy stuff I don't see why you need to enter guitar pitch territory
