I'm playing(I use that term loosley) a Fender Deluxe Active Jazz bass. I have had Fender flats on it since I got it, and am ready to try something new. I definitely want to go round wound, and am looking for some growl. I don't know much about string brands and types since this is the first time I've changed them. I have heard that certain strings mess up your frets, and I'd like to avoid that. I mainly play blues and classic rock. I would appreciate some suggestions of what to try since there are so many choices out there. The first thing that comes to mind are Rotosounds and Boomers. Thanks for the advice
