I would start with some D'Addario nickels. They are cheap, sound decent on an EB-0 and are a great starting point for getting your sound. You can decide from there whether to go brighter (steels) or darker (flats or tapes). I have an EB-0 which I have made it my personal mission to make sound good because it's fun to play, but if I were you I would save the money you would spend on string experiments and get a used Squier P bass or something. If you are stuck on the EB-0 then use it for what it was meant for and get some flats or tapes on it. Anything else sounds tinny and then you will have to replace the pickup. Again, by the time your done making it sound good you could have purchased a cheap p bass or jazz bass. I am only making this recommendation because you are so new to the bass. You should be practicing instead of noodling around with a niche bass like the EB-0. If you are stuck on it then have a Dimarzio Model one pickup installed. It will help your tone tremendously.
