I had been looking for this type of string set for a long time because I had a level drop between the G string and the B string on my Strat equipped with Texas Specials... I used to modify a standard 009-042 set into 009, 012, 015 to have a 003 offset between each treble string, which is expensive because you have to buy the 12 and 15 strings separately... So I am delighted to have discovered this set.
