Okay I took a moment to take a few quick pics and give my first impressions. The first couple things I noticed are exactly what I liked about Ken's LM5 and what made me place an order - the neck is absolutely perfect. Nice and wide across the fretboard, and thin from front to back. Also the neck pocket is set so there is enough room to dig in if I need to, but the pickguard is still very close to the strings. I guess it's hard to explain why those two things are so important to me, but they REALLY make this bass perfect for me in terms of playability and that's why it's so hard to put down.
So I plugged it into my small rig (LMII into an LDS 112/coax cab) and whoa - it sounds exactly as I imagined - super aggressive 70's jazz with TONS of grind and punch. I'm LOVING the preamp. Feels great on a strap, very balanced. I weighed it on my digital bathroom scale and it comes in at 10.4 lbs.
So here's some pics from my iPhone...they don't do the 3TS justice but they'll give you an idea:
