I have one in for a review, so here are my first impressions:
The bass really looks good! The colour is so much nicer in real life.
It feels like a long scale, because of the long body and modern P-ish 41mm nut. Well, maybe it doesn't feel ling scale while playing, but it doesn't feel like a toy as a Musicmaster does. (I'm 1.90, which is almost 6ft3 in the strange measurements of you 'Muricans;) )
The middle pickup is positioned at roughly the same place as a Musicmaster, but it sounds opener and brighter.
I can use the three pickups as thumb rests. No problem.
My favourite sounds are:
B/M: tight, Fender-ish, cutting through a mix but with some sub low-ish sound to fatten things up.
M/N: Warm, woody, but still open and aggresive. Never muddy.
M/N, tone rolled off: Vintag-y warmth.
I think you have to play a bit with pickup heights, but the push/pull ads zero to nothing to N or M/N on my review example.
Two other things: the body of this one's really light (the overall weight is just okay) and has some very pretty grained rosewood. A stripe in it. I do like the strange dot positions.
