Firstly, save yourself a lot of cash initially and get set up with some roundwound strings. For me, strings have a huge impact on tone and really bring the electronics on your Bass and amp to life.
Also, more importantly........Jaco used Rotosound roundwounds (if I remember correctly) while Victor Wooten uses D'addario or Fodera.
A set of Nickel D'addario XL's would be a great and economical start since they are available quite easily, plus wouldn't be too 'rough' a jump from the smoothness of flatwounds. Not to put you off of pedal buying of course, as I'm currently a pedal-junkie, so any extra tone-shaping can always be fun
