I have had my Fender MIM Jazz Bass sitting in my basement for sometime. I use it once in a blue moon and I didn't really pay attention to its tone. Now I'm thinking about using it on more reqularly and I wonder if I should put some new pickups in it to get better sounds. Are there any bass gurus out there that play mostly blues, rock & roll, country and ballads and wish to help me out. Or may be you consider the sound is good enough already and I shouldn't even fool around with it? Any suggestion is appreciated. I seldom slap my bass (unless it gets really naughty, hehe).
