It sounds pretty good, I would say "modern" if that makes sense but nothing like that one I played at Emerald City Guitars....
FWIW I saw a post by Rob @Basvarken regarding a new pickup that is faithful replica of the ones used in the late '60 Les Paul basses, hopefully he'll chime in.
I guess it's a low impedance stacked humbucker made in conjunction with Gemini
Who is this wanker?
Yes! I'm super excited about this.
Thank you for asking Mark.
Last weekend I installed the prototype of the Brooks Gemini pickup into my modified golden oldie Epiphone JCS.
The pickup is a dead-on replica the best sounding bass pickup of all time: the Gibson low impedance stacked humbucker that was used in the Les Paul Bass between 1968 and 1979.
At least in my opinion.

I really think they're amazing.
Extremely silent. Magnificent dynamic response. Tight low end. Chrystal clear top end. And very versatile.
For years I roamed Ebay and Reverb to score them to put in various bass guitars. But last few years they've become as rare as hen's teeth. And when you finally do find one the prices are astronomically high.
Many times I tried to find a pickup maker who can replicate it. And many of them said they could. But in the end they all had to admit they couldn't.
Until now!
Gemini Pickups from the UK joined forces with Brooks.
I sacrificed an original and carefully dissected it. Which was not a sinecure by the way.
The pickup revealed its very unusual architecture. And step by step we reverse engineered it.
And now the first prototype is alive!
If you have any further questions I'll be happy to answer them.
