My old pbass has a bit of a back bow so i'm looking for some strings with higher tension to pull the neck back. I've been playing chromes and enjoy the feel but don't know if i am completely sold on flat wounds. Does anyone make a mellow high tension round wound? Or should i try another brighter high tension flat wound? The bass is a 72 fender p bass with a maple neck and fb that tends to sound bright with D'Addario rounds. I'm playing a lot of rock/garage and even some punk stuff with the bass.
