I am just getting back into playing bass after a long hiatus, and I am getting an Ibanez AEB10E acoustic purely to practice out on the patio (translation: "anywhere the wife won't get pissed off at me"), and maybe to jam with my daughter, who is just starting learning guitar. I don't see performing with it (I would get an electric if I did) beyond jamming, though being able to plug in and get a good sound would be nice. Any recommendations for good roundwounds for it? How about flats? Anyone tried Thomastik Jazz Flats with it? And why are acoustic bass strings phosphor? Is it purely aesthetic, or do piezo pickups need it? Thanks for any insights.
