Ok well I just got into bass....I played guitar for a few years quit and decided 20 years later I wanted to play bass. I bought a new fender jazz....been playing it about a month with stock roundwounds. I just got a setup the other day and had him put on La Bella 760FL flats. at first I loved them they were so smooth and nice on my fingers. now they feel like they are square strings! literally square! like I can put my plucking finger on the E A D and they feel like they have flat spots all along where I pluck! now is that a normal feeling for flats? or is that normal for your fingers to get like that from playing so much? or is it all in my head? the strings feel square!
