Finally, yesterday I picked up my guitar with my new BK combo, and I can only say... WOW

The result has completely exceeded my expectations. I can't imagine a pickup that suits better to this guitar (and my way of playing, of course) than Abraxas bridge. Is hot enough to play even metal (nothing to do with the PRS#7), deep but clear and defined, not sharp at all (it has a great mellow cleans too), and respects the tone of the guitar in spite of being a quite hot pickup.
And what can I say about the mule neck?? This pickup just blew my away, probably one of the best les paul neck sound that I've heard. Veeeery deep, but not too bassy and with the right amount of highs/mids to not sound dark or muddy, sounds amazing both with cleans and distortion, and can handle perfectly a high gain amp.
The coil split is not very impressive though, but I think the overall sound of the combo worth this lack
