Thanks mate that's great, that's exactly what I'll do, when I bought the bass the bridge saddle for the E string was missing and the set up was pretty bad! The bass is set up Ok now with the bridge saddles out and a few pieces of cardboard lol I've ordered a new bridge for it just to get the saddles as I couldn't find them anywhere.
When they arrive I'll file them down and hopefully that will sort the problem out, I'm surprised how well the bass plays.
