ive had this bass for the past 3-4 years ibanez edb600 but i feel its time to buy another, i plan on going to guitar center to play some basses, but i cant decide right now on how many strings. should i get a better 4 string, a 5, 6, or possibly even a 7. now while id get 'props' for my 7, i have no experience playing one let alone 6. i like to play (attempt to play) victor wooten's, stu hamm's and some les claypool stuff. also what do you think about tremelos? some of my friends think that the sound may be a little weak with one. thanks for the help.
