I think it's about time for me to change the strings on my bass guitar but I realise I have never bought a set (obviously aiming for the Motown dead string sound :)!).

Any recommendations for what gauge of string to buy and what the advantages of different gauges might be?

It's an electric bass and I play a mixture of music from rocky stuff (All Right Now/Blues/even a little metal when I play with my son) to folk music.
