The TLM49 has NO tube like character, at all. I'm sorry, but that "tube emulation" circuit doesn't sound at all like a tube.
The TLM49 is not a flexible mic. It sounds good on some vocals, but the high mids get unpleasant on some sources to me.
But if you want to see what happens when you shoot it out against a U87 and a M49, read what I wrote (well, almost ... because they edited out the negative things I had to say):
