Hi, First I' m a jazz bass player with rotosound 45-105 rounds. But I will try to play in a stax/motown group and will have to try a diffrent kind of setup. I will a play a RI'62 Pbass with a 230 acoustic amp.I know acoustic is not ampeg but I will not try to use my swr baby blue for that.The acoustic is not that bad I think. So I want your opinion for a set of bass string with this setup. Do you think flats are necessary the best choice ? And what gauge and material ?
