I bought these to re-string an old classical guitar I had rescued from a pawn shop about 15 years ago. After scouring through dozens of reviews on various strings, I chose these primarily for the composite G string that is included in the package. The strings were all of good quality (none unwinding right out of the package) went on fairly easily, and stay surprisingly in tune. I am still having to tweak the B and E each time I pick it up, but the rest of the set has pretty much finished stretching. I am pleased with the overall tone . . . the bottom is nice and deep and the top end noticeably bright. I do think the composite G string (which is a cream colored string) does help balance the sound between the low end and top end. I would definitely buy them again.
