The BB1 & BB2 are probably great for what they are but it's not what I want to hear from my electric guitar, especially from a Les Paul.
My ideal LP tone has to have balls and heft, yet be tight and gainy with distortion and balanced with cleans on both pickups, the JB/Jazz(59) set checks all the points above whether the PAFs don't.
Also, I'm probably used to my Edwards LP which has the JB/59 set and was my main LP guitar for 12 years, so I was kind of expecting the same if not better sound from the Gibson but was disappointed.
