sounds like me a few months ago! seriously, for a while i just couldnt get bass nailed at all!

its all stuff youl have to learn along the way, as everyone on here has! there are so many different ways and techniques for creating basslines, and there are more than 1 topic on here about bass so have a search!

big props go to Ze Migl, he has helped me alot in this area and in general!

da man!
