The G string is just what I'm looking for, has that "out of box" brightness, and an emphasis on the fundamental. The D and A strings however, have no "out of box" brightness and sound like they're ready to be changed even though ther're brand new. The E and B strings have no overtones whatsoever, and are just thuddy bass notes.
Incredible differences between strings, I don't know where to put these on a 'brightness bar' because there are 3 different tones in the same box!
I've learned my lesson, will not buy D'Addario half rounds again.
