Ergonomically they're mostly great, but the reach to the first fret actually felt further away than on my Dingwall. The fretboard is obviously a pretty flat radius, which I liked but obviously some would disagree (I felt like the fretboards were comparable width and radius to the 5 and 6 string BTBs, but I've only screwed around with a couple BTBs in stores and haven't compared the actual measurements so take that for what it's worth).
The Nordstrand pickups are awesome. It seemed like the full frequency range was on tap, which I personally prefer. Not much more to say about them other than I guess in a perfect world I'd position them differently but that's just because of my own idiosyncrasies (for example, my pickup arrangement on my Dingwall).
Though I mostly play active basses I leave all the EQ settings at noon. That said, the flexibility of the mid sweep in the preamps the EHBs have is incredible. The range of tones available from just what's on the bass is awesome.
They are LIGHT. Like, stupid light. If someone places a lot of importance on weight, the EHBs should be at the top of the list of basses to consider. Personally, though, I think I prefer solid body basses. Now, that could just be pure coincidence but over time the Dingwall has become my go-to, though I also love the SRMS bass I have (and the one I used to have) which is solid body. I'm not going to say that solid body is better than chambered, because I think my experience is purely anecdotal.
Though I think the EHBs look awesome (especially the TSF which they mysteriously don't make anymore), the finish felt like it might not stand up to much abuse. I don't slap, but I saw an EHB for sale here that had the finish worn completely through where the guy put his finger when popping (I presume). Considering these haven't even been made for all that long, I wouldn't trust the finish to go the distance.
I think the headless system Ibanez uses is great. It can use normal strings and it's easy to change strings (though if you wanted to use some absurd bridge cable like bigger than a .170 it might not fit...though I didn't try that to confirm). I also like the look of them, though I understand plenty of people can't stand the look of headless. It's also easy to make really fine adjustments to the tuning, which is nice. Never having to worry about it getting bumped out of tune is also nice.
Overall I think they're great basses, with the weight, pickups, and the headless design itself being the stars of the show.
