Hello all.
I tend to favor pure nickel wound strings. I like Ernie Ball's "classic rock n' roll" strings, GHS "pure nickel" strings, GHS "pure nickel, slightly burnished' strings, Fender pure nickel bullets, and Gibson's "vintage reissue" pure nickel strings. I like the sound of pure nickel strings right out of the package.
I also like nickel plated steel wrap strings. My favorites are Ernie Ball, GHS, Fender bullets, and Gibson bright wires. To my ears, nickel plated steel have a very bright sound right out of the pack, but after a few hours of use they tend to mellow similar to pure nickel strings.
On my strats, I tend to use .009-.042, on my Les Paul I almost always use .10-.46.
