I would like to know when roundwounds were invented for bass, and by who? The reason is I want to find out if my favorite type of bass music was recorded on flats or rounds. I would also like to know if these people of old played with picks or fingers or thumbs. Jamerson, Kaye, any of the Motown people, Lesh, Cassidy, McCartney, so on. I can't seem to get the pick thing down, should I try? I like the deep, thuddy sounds. I play with flats and I am starting to use a foam mute. I know I am WAY old skool, but THUMP is the sound I hear in my brain. I have all sorts of different basses, most with flats. Do I need to learn to use a pick? Or should I just let my flats age?
