About 14 months ago, I succumbed to the TB induced gas and finally tried flat wounds on my P bass. (LaBella) I love them and thanks to bassstringsonline I've been experimenting with lots of strings during the past year. Anyone use flats on a 5 string? If so, how's the B string? Would there be any advantage to using a SS round wound in the B string and the other 4 strings flats? I ask that because I've noticed that SS strings are more articulate (IMHO) than other less bright strings for the low B. my current #1 bass is a Valenti 5 string with PJ pickups. I am looking for a good rock tone. Sorry for the ramble. Any opinions?
