And that's exactly the point I've been trying to make all these years;
home recordists can make perfectly acceptable recordings with a lot of the new crop of lower cost microphones. We do not own one single modified microphone at our studio. (I lied; I do have a couple of old Fairchilds that Dan Kennedy modified to run on phantom power.)
All the MXL's, the Studio Projects, the Avant's, and the
Behringer ECM8000's (and every other mic we own) are straight out of the box and that's what we use.
A U47 or 48, or 67, or a U87 can be a fine choice for a lot of vocals, but sometimes, it can be beat by a less costly mic. The
Shure SM7 comes to mind as a notable example. But the MXL V67g (with a little eq fiddling) can get you close, too.
Don't have an old Telefunken ELA M251, or an AKG C12? Try the Studio Projects T3.
Please, try to just listen to some of these new mics with an open mind, and consider the person singing into the mic, not the brand, or where it was made. It should be all about what's best for the singer (and your budget).
