Wow, I watch your reviews all of the time! I didn't know you posted here! Pretty cool.I just finished writing a review of the Hen-Bev bass for Guitar World. I know nobody here READS that magazine.... my dirty little secret is I've been writing bass reviews for them for 7 months or so...
Anyway, I spent a lot of time with one, and did a video demo of it (which will be posted on YT when it comes out in print).
I felt it was too expensive, but... it was a cool bass. The tension-free neck and the through-body individual bridge give it a very clear tone. The sustain and note purity are exceptional. Now, is it for me? No. I'm not a big sustain nut. Half the time I'm either palm muting or stuffing foam under the strings, so... not my taste. However, if you like a ringing, sustained tone with lots of individual note clarity... this bass does that really well.
The EMG Hz pickups are getting a bad rap I think, maybe because people are confusing them with the cheapo EMG Selects. HZs are EMG's passive pickups, they sell for around $200 a piece, they ain't cheapos. I thought they sounded good in that bass, they have a certain pristine quality that matches up with the intention of the builder.
Again, is it for me? Nah. I've been moving further and further away from a bright tone. Flatwounds, foam, and really old dead roundwounds are what I like these days. To each his own.
Enjoy the bass Jauquo!
EDIT: Under their FAQ it says that you can supply your own pickups with the same dimensions and they will send it to you with those instead.
Still might cost the same though.

Now I have a great pic of him
