i'm going to go buy myself an sx or brice fretless jazz bass today. i'm looking forward to creating a monster of a bass out of it, yet have never done anything of the sort before. what i'd like the bass to do: have lots of punch, be able to cut through a mix against really loud drums, have lots of bottom, a decent amount of high (but not sizzly highs - i hate that), heavy on the upper mids.... ummm, and i'd like to remain passive as i don't wanna throw TOO much money into it. my 2 favorite easily identifyable bass sounds are jaco's and flea's. wouldn't mind being able to get a motown like sound out of it also. ok. i'm aksin a lot here, but i'm going to shoot for the stars. what i'd like from you, please, is to start making recomendations for upgrades, bridge, pickups, anything that would bring the above closer to it's reality. if possible i'd love if you could include the price of each item, and what you think the item helps the bass to do. example - i hear everyone talking about putting a badass bridge on their basses. how does this affect the sound? i don't have a clue. does it give the bass more bottom??? more punch? more clarity? does it weigh down the bass a lot. anything and everything is mucho appreciated. thanks.
