Re: Thoughts on Gibson BBPro pickups . . .
Well, I don't love them...but they've remained in my 2004 LP Standard '50's Neck since I got it brand new 15 years ago.
They are a lot like '59's...but "better," IMO. They have the kick of '59's, but with a more biting top end.
They are on the hotter end of "vintage" PAFs. The winds are not too hot, but they have those A5 magnets, which are. They are tight and blocky, but also thin up top (in a good way). They don't do so great in low headroom amps, unless you play the amp relatively cleanly and quietly. The neck one can be really hard to dial in without blocky mud, unless you play through an amp with plenty of headroom.
I keep saying I'm gonna put Seths in that guitar...but I've been saying that for 15 years...and the original pickups remain. I could easily have added Seths at any time...but I haven't. That says something. Not everything, but something. I still say I'm gonna put Seths in...and I still don't.
If the bridge pickup sounds thin, try raising it, and/or backing off the tone knob just a hair.
FWIW, in my guitar (2004), they were called Burstbucker V's. They changed the name to Burstbucker Pros not long after, maybe by the time your guitar was built (2006). They are the same pickups, though; it was nothing but a name change.
Also, they came in #1 and #2 models – neck and bridge – which are not to be confused with "regular" Burstbuckers 1 and 2: alnico 2 powered pickups that preceded the Burstbucker V/Pro.
P.S. I've long though that they would be really good with lower – but not too much lower – powered magnets. Perhaps a demagnetized A5, or an A4. But I've not tried any swaps.
