I jumped on the wagon early on. After many years of playing round wounds on all my basses I started using flats about 10 years ago on my p styles. A few months ago I decided to put a set of rounds on my U.S. Lakland 4451m. So fresh to my ears. Piano like tones that I've missed. The band seemed to notice for the better. (But what do guitar players know) Not saying that I'm back for good. I keep my 72 P with flats for now anyway. But I'm digging the sizzle.
