I am learning a bunch of rock tunes for a new band, including tunes by the Eagles, Doobie Brothers, Foreigner, Journey, and Steely Dan. I know many of the bassists in these bands played a Fender Precision. I own a '77 P bass, and I can't get it to sound like any of the above bassists. I am using Ernie Ball Slinky strings, which are round wound. Should I be using flat wound strings to achieve a more authentic P bass sound from that era?
