I wanted to make my Gibson Les Paul Custom Shop 59 vintage sounding, The Gibson Custom Shops come with Gibson Pure Nickel on, I tried a set on my guitar but it just didn't sound right, Pyramid strings seem to come up a lot when I was looking for good Pure Nickel strings, I put a set of "Pyramid Nickel Classics Regular010 - 046" on my Gibson Les Paul and I didn't want to put my guitar down, it sounded like my idols use to sound with their Les Pauls, Rock / Blues / Punk and Great for Solo's.
YOU MIGHT NEED TO HIGHER TO BASS SIDE OF YOUR PICKUP BY HALF A TURN OF THE ADJUSTMENT SCREW?
Because they are Pure Nickel the wound string are very slightly lower output then Nickel-Plated strings, this is how they were in the days of old.
