I have to fundamentally disagree on the Emerald bridge lacking bass. Granted, it's certainly not bassy but it has controlled bass. It never sounds thin, it doesn't have low-end flub, but notes and chords have plenty of weight to them. It's a very even pickup, overall, with a sweet top end and lots of presence and rich harmonics. String separation and clarity is impeccable and the splits are great - quite Tele-ish in the bridge.
I've got in a Les Paul that is quite bright, acoustically, so having read some of the posts on here I was concerned before I ordered it, but it's absolutely fine - for example, I'd say the Mule is brighter and less bassy, even if what low end the Mule does have is "looser", so it responds differently. I've lived with it for four years now and it is absolutely my favourite pickup for a Les Paul.
Now whether that translates into a PRS is another question, but I think certain very visible posts in this forum paint the image of the Emerald bridge being thin and shrill, and that couldn't be further from the truth at all.
