I had the wonderfully timed luxury of having today off and almost all to myself, the day after the bass arrived.......so I spent 4 hours playing her.
Preliminary joyful impressions:
Fit and finish: this is the most finely finished and esthetically beautiful bass I have ever laid hands on, and I have been fortunate enough to have played many other boutique basses. The "Stormy Blue Monday" burst on the outrageous burl maple top is nothing short of hypnotic in person.
Basics:It weighs 9 1/4 lbs and balances perfectly both on the strap and Knee. The neck feels smooth, not tacky at all and is very hand-friendly.
Came in the Dingbag-one of my few niggles at this price point.
Sound-I haven't heard it in a mix, so take that into consideration. This thing has such a wide array of tonal options within it that mining them can become an all-consuming obsession. The pup selector can choose neck or bridge soloed, both bridge pups in a "punchy humbucker" config, or the calssic bridge and neck pup combo. In passive mode there is a passive treble roll-off available as well as coil tap switches for the neck and bridge pups. The Glock pre adds 3 band eq with sweepable mids. I love the soloed neck pup and, to my surprise, the punchy humbucker mode the best. I'm generally not into the Musicman thing, but for some reason the 2 bridge pups on this baby just kill, and sound fuller to my ear than a 'ray bridge pup. The clarity of notes down through the lowest B is stunning, as with every long scale Dinger I've played. Usually I like passive basses, but the Glock pre is very musical and powerful and it won me over quickly. The stock Dingwall strings are super bright, which will please many, but IME I like 'em when they're deadened a bit. There's very serious growl in them even when broken in.
All in all I think my other basses are in for some serious down time, at least the ones i haven't sold yet

I'll post more after I play it with the band. I know the no pics no bass rule, but I can't take pics as nice as the ones Sheldon posted earlier.
Thanks Sheldon!
