Hello, and thanks to all who responded to my question.
I am going to take Keith's advice and install Thomastik-infeld Jazz flats.
Pauldo, what good eyes you have. Yes the stings on the bass now are a very old set of Rickenbacker electro flat wound.
I didn't like them at first, but getting to like them more. I originally had on a set of Rotosound Spacers which were round wound, I believe, and liked them. However, Rotosound no longer makes them because they told me they were too expensive to make. There is a very different feel between round and flat wound strings. It took me awhile to get used to the new feel. Now there must be a reason for Thomastik flat wound strings being so much more expensive than other flat wounds. Well, I'm going to find out if that is true.
Again , thanks for your help.
