Ah, sorry. Brain fart...
That's the ADK Vienna and Hamburg.
I've been pretty thoroughly unimpressed by the Hamburg. It sounds harsh on my voice, even through a tube pre (not toob). Natural and rounded, it is not, IMHO.
I've been really impressed by the ADK Generis tube mic, though. Flat out gorgeous tone, IMHO. Definitely worth looking into if you're a tenor. (Thanks, ljmaxx.)
I've also been quite impressed with the Chinese ribbon mics, particularly when modded with a Lundahl transformer (the Shinybox mics, for example). Very smooth sound, not at all harsh, but also not by any means dull.
For guitar, I'd second the Naiant MSH series. I don't think you can possibly go wrong with the MSH-1 series. I'd even be tempted to go with a pair of MSH-4s, one at the sound hole, one up a few frets. Haven't tried it, though. My pair of (current rev) MSH-4s is on order. I have one of the original rev, and IMHO, it's pretty sweet, but I wanted to have a second, and dang it, he redesigned it, so now I have to buy two to get a pair that are even remotely similar.
*sigh*
Also, for guitar, I've found a pair of Studio Projects B3 mics in a M-S arrangement to be good (one in figure-8, one in cardioid). I also found it to be sound quite good using an AT2020 as the cardiod instead. YMMV. A lot of it depends on the sound you're looking for.
