Very nice pickup
These are killer pups. I have them in a Les Paul Studio (worn brown) and just love them. It's funny - they smoke the stock 490R/498T combo that comes in the more expensive LP Studios, and the BB Pros are the usual pups in the cheaper LP Studio.
These remind me of the Vintage PAF type pickups in their EQ and shape, but are hotter all around. They get aggressive easily, and can hit the front of your amp pretty hard. I had to completely restructure my amp and effect settings when I started using the LP, because these interact so differently from the stock 490R/490T set in my SG, and the DiMarzio 36th Anniversary PAFs in my other LP and my other SG (which are also killer pups, in a more vintage way).
For me, versatility is the name of the game - and these pups can do it all. If you need cleaner, roll back the guitar's volume pot a bit.
