I have a copy of Wisper Not by the Peterson trio which I date to the early 1960's. The bass sound is exactly what I an striving for. I know that Ray used steel on the bottom with gut on top for a long time but the lower strings don't really sound like spirocores to me. They don't sound like wound gut either...more like something in between. Does anybody know fur certain what he would have been using around this time? It might be the lush sound of his bass that I am hearing, and the strings are not the key. I don't know.
