O.K., I just recently bought a Fender American Deluxe Jazz; on the Fender site it says that the Bass is strung with Fender strings (7250M) Nickel plated; anyways, the strings sounded really good when I got the Bass, but I figured, it'd sound even BETTER with a brand new set of my favorite new strings on it ... Right? - WRONG!, I left the new strings on for ? 7-10 days or so, then decided, 'Let me put those first strings back on (for Sh**s and Giggles); Man when I tell you, that Bass CAME BACK TO LIFE! (the strings were never really dead to begin with). So anyways, I'm used to Fender strings having those color coated ball ends, but these "Fender strings" aren't color coated; so it's got me thinking, Are these really Fender 7250M's?! or could they have been switched somewhere along the line before it got to me? They sound fantastic! I would buy a case of 'em if I knew for sure what exactly they are, Ha!!
