This set was purchased from a reputable talkbass member, JohnnyAlien and put on my Fender American Jazz bass strung thru the body. They fit perfect and barely cut them (I prefer more wounds over the tuner). I put them on for 5 min and pulled them. They are great and not even yet broken in. I just prefer steel strings and went back. They were worth the try. Like I said, they are virtually unused and still need to be broken in. Sorry for the crappy iPhone pics. $20 gets them shipped to anywhere in Lower48 USA! I think I paid $29 or something.
