i got some strings on my bass that keep buzzing when played. not sure if it is to do with the bridge or up at the head where there kept in place or if i need new strings???

ideas welcome

thank you
You need a setup. Ben has done a good job of explaining how to do this in the FAQ, but if that doesn't make sense, take it to your local shop and ask if they can show you how to do it. This can happen if you change gauges in your strings or if the weather changes (say from hot to cold or visa versa) and your bass' neck goes out slightly.
yea thanks for your help, found out it was something loose inside the guitar which was vibrating when playing, so i'm gonna get it repaired.
