Ordering this strings for my lil brother since he only have HB student series SG type, which is medium scale and custom gauge like this is really seldomly available on our local store.
This strings does help big time since at this time, my brother's composing their new songs which required Drop A tune and he refuses to use my baritone guitar since he wanted to use his own instrument, for his own accomplishment.
I can't say this strings durability is good for you or bla bla bla since every strings react differently to each person. My brother cannot use the cobalt one without corroding it after a week, but this one always last at least month before start to corrode.
If you want it clear sounding profile, then it is for you. I personally like this strings but cant stay long with me.Even pricy DR cant help me except D'addario..My advice, search for your right strings doesnt matter the price..This though I recommend it for starting point.
