Well I read all 45 pages of this thread, Pooped my pants, then popped for the pickup.
Played my first rehearsal with it last night, loud sextet playing some pretty bombastic music. Sounded and more importantly felt absolutely amazing. I play a lot in our jamspace without the amp, and I felt like I could use the same touch with the amp; my normal playing, just a little louder. Setup was the Y (E side only), an Fdeck on my quiver, into a Traynor sb112. Everything flat, and the mid scoopy thing (that I normally almost never use) turned up a little under half way. Perfectly usable sound.
At one point I had turned my volume off at the fdeck and accidentally played half a tune no amp and it wasn't immediately obvious. I just thought "I need a little more juice" and looked down and saw that it was off. That's a sign that, at least at low volume, in that space, the pickup didn't add anything distracting to my sound.
I have a tentative duo gig with a guitar player this Sunday in a nightmare of a restaurant (all glass and polished concrete) which will be a good test. Then at the end of the month a gig with that same sextet in a nice small club. Will report back after that.
Build quality is top notch. The thing is even serialized which shows the maker stands behind it, and doesn't consider his pickup to be a "consumable" product. I've used the Underwood for the longest time, but I've owned both realists, a full circle (at the beginning of my playing, sold it when I got the underwood), Ehrlund (couldn't get a reliable, consistent sound) and an early Krivo. This pickup on build quality alone is a step up from those (though I can't compare it directly to the Krivo or the Ehrlund, different things entirely) and so far soundwise was the easiest to dial in a workable sound, and still felt like I had plenty of information to dial in more clarity if I needed it. Very well executed design that doesn't clutter up the bridge. Only technical thing is its about double the thickness of my old adjusters, for now the height is good but I have them down all the way, if I go to a tighter string I may need to do some bridge work, no biggie.
