Most guitarists I know tend to buy the typical 80/20 phosphor bronze strings. These are 92/8 phosphor bronze and it really does make for a nicer sounding string. The unwound E and B strings are bronzed. If you aren't into the nano-webb strings (I'm not)to get long life out of your strings, try these, the do last longer than the 80/20's. I use these on my D style as well as a Martin OOO, sound great on both for bluesy, fingerstyle playing.
