Got a J-45 vintage (2019 but “vintage” model style with the banner logo). Amazing guitar, though I’m looking for the best set of strings to use with them... right now the B string is a bit thin and buzzy sounding..erhaps it’s the setup? Any suggestions on getting the B string to sound full? Mostly noticeable on lead lines. Not sure if a different type of string will help, or if it’s a problem with the nut?
