Uh ......... nothing worth yelling about. Just strings there sugar blossom.
Yes, it is worth yelling about. The day the new Fender Flats came out, a g##d### urban myth started about their construction and tone, and it just isn't true. Whoever may make the strings, they are made totally differently:
1) the cores are different;
2) the wrap is a different alloy;
3) the wrap ribbon is a different width;
4) the wrap wound the opposite direction;
5) of course, the silk is different, as minor a detail as that is;
6) when you hold them side by side, they are different colors;
7) the feel is different -
for the same gauges, the Chromes seem to have a little more tension.
8) the Fender flats, somewhere on this forum is a spectrograph that shows after each has settled in, the Chromes have a spectrum peak at @200 Hz, and the Fender flats have a spectrum peak at @600 Hz.
The only thing that can be said in comparison is that they both sound great on Fender P-basses, depending on what kind of tone the player wants. BUT THEY ARE DIFFERENT!
So YES, I am going to KILL this urban myth, whatever it takes.
