I just bought a 3-pack of the new "Classic" strings (10-46). I typically use EB Slinky's on my McCarty and CU22. Honestly, I couldn't tell a difference. All strings, when newly installed, sound better than what was on there before, so it's hard to compare. The only true comparison would be to put new strings on two identical guitars, and compare them that way. Maybe I don't have a discerning enough ear (or I have rock 'n roll hearing), but I generally have 3 categories for strings (of the same gauge/wind/alloy):
1. Expensive coated strings
2. Cheap and
[email protected] strings that break, or tarnish and go dull quickly
3. Everything else in between.
I generally will use D'Addario's, Ernie Ball's, RotoSound, Fender, or any other name brand in category 3, with similar results. I'd say that these PRS Classic strings go in category 3.
