String Forum Rules:
1. If you're going to ask what kind of strings you should buy, make sure you FIRST look through all the links below, then do a search. If your question isn't answered, then make sure you include your bass, your playing style (pick, slap, finger, etc...), what kind of music you play, and what/who you want it to sound like.
2. DO
NOT POST A POLL unless you have a darn good reason. 'What strings should I buy' isn't a good reason.
3. USE THE SEARCH. there's only so much ground we can cover in the strings forum - so no question is a new question. If you search, you'll find the answers RIGHT AWAY, whereas if you post, you have to wait for someone to answer your question.
