I have been playing Gibson Les Paul's for 15 years. I have had just about every Gibson humbucker made including, 57's, BB and BB Pro, 490R and 490 T, etc, etc. I have never felt the need to swap out these stock pickups but lately I have been wondering if there are improvements to be made in clarity, punch and articulation. I play crunchy hard rock stuff. Think Clutch, Zeppelin and ZZ Top. Any of you guys replace the stock Gibson humbuckers with something else and been extremely happy? I also can't see myself paying upwards of $500-600 on new pickups so the boutique, ultra expensive stuff is out.
