OK, I actually went and picked one up.
Now that I have it into familar signal chain, I'll have to tone down my earlier comments. The pups are VERY good, but not over the top. The output is a hair lower than a good passive Jazz. The really cool thing is that the pups have a similar dynamic response to single coils, but without any hum at all; great harmonics and lots of punch. They will not replace J's for a die hard single coil Jazz vibe. However, they are very close and a ton better than the humbucking versions out there.
The tone controls are pup toggle, volume and tone. Although the circuit is passive, somehow the tone pot is not just cutting treble. It actually acts like a boost control going both ways.
The bass itself has a great design. Tiny body - the whole thing weighs in at 6.10 pounds!
I'm still struggling with neck setup and strings - you know how that goes, new bass.
They go for about $750 out the door. So, they have about that level of quality in the lutherie. Not totally shabby, but it will take a bunch of tweaking to dial in the setup.
Overall, a pretty cool bass for what it is; and I think the pickups have some real possibilities down the road.
I'll try to post a pic later, but it is essentially identical to the OP, but with trans blue wings.
