A vague question like that would only get vague responses. Here's my vague response... Whatever string that sounds good and feels good to you.
You are right, I want to change a little my questione: what are the strings shipped by Fender with this instrument?
When I bought my Fender Ultra P it had 7250's installed. Planed on changing but Bass sounded great as is. Kept them on 9 months then changed to Markbass Ultimate (2.5 times price] If all I could ever use is 7250's I would be fine with it.
After trying all kinds of strings, I have settled on T.I. Jazz Rounds for my Roscoe Beck 5. The upfront cost is steep, but as I get 5 or more years out the T.I.s, with them maintaining precise intonation, and having a great balance of harmonic overtones for my purposes, the cost amortized over the life of the strings makes them one of the most cost effective.
