I play Gibson guitars. I am not a big fan of Gibson pickups. So I always switch them to Seymour Duncans. I have several guitars and they all have different sets of Duncans on them. The SH-4 JB is by far my favorite! The sounds I get with them thru a Boss GT-10 is unbelievable! The SH-6 is my 2nd. I have been playing my entire life and I am here to say that Seymour Duncan pickups are the BEST! I take out Gibson 57s, Burstbuckers, Dirty Fingers, etc, and replace them with Duncans. 5 stars is a low rating.
The sound is Awesome. Changed my sound of the guitar from using it when I break a string to using it heaps now! Strong and Powerful sound that is amazing!
