I've never really cared about the sound of strings until now : A few months ago I bought a new Fender P American Deluxe. I absolutely loved the growly aggresive sound. But a few weeks ago I had to put new strings on it and it seems to have lost the 'growl'. I first thought this was because they were new, but I already did some concerts with it and still no growl. I always used D'Addario nickel wounds EXL160 for my other basses, but with the Fender P, I don't really like their sound, still aggresive but no growl. Can someone recommend some 'growly' roundwounds? Or does someone know what strings Fender puts on their new P basses when they come from the factory? Thanks, Peter.
