I have, and sorry if I missed it but I didn't see any before/after discussions which went into any depth. I did listen to the video of the pickups themselves (which sounded great indeed).
I'll give it a go. I am not great at describing sound.
I replaced the standard TB +s in my 08 Gibson TBird with a set of nominal 9.2s EY Pickups (that is how they are listed on the seller's website).
According to my multimeter the TB+s were both around 9.7K, the EYs measured around 9.5 and 9.6K, neck and bridge respectively. I put the slightly higher resistance one in the bridge position.
The EYs, to my ear, are considerably clearer, have more top end and more pleasing mids.
I found the EYs easier to balance across the strings and between pickups than the TB+s had proven, which I found to be very sensitive to adjustment.
The bridge pickup needs to be cranked up to maximun height on the screws provided (ie the bottom of the pickup level with the top of the body of the bass and the top of the pickup about 5mm from the strings) to get enough out of it.
I am mainly a neck pickup player and so the bridge pickup is giving me enough with the current set up- some may want more. I can lower the bridge itself a little still (there is still some downward adjustment available on the "front" post, but haven't bothered yet. as I have a chrome 3 pointer and tuners on the way and will fully set the bass up when I change the bridge and tuners over.
I have used the bass with the band now- it cuts through better with the EY pickups and sounds "more musical" for want of a better phrase. It also has better sustain. Still plenty of power. The bridge pickup is similar in fullness to my Greco Single pickup TBird- but probably not as angry sounding.
Told you I wasn't great at describing sound. Hope that helps a little.
Here's a pic of the bass partially blinged- they do look the part!
