Hey Frets. Sounds like we have a lot in common...except I prefer a warmer sound, especially for my vocals.
I think an interesting aspect for me is more the combination of mic and pre. Again, this is for male vocal (my voice is not "thin", but definitely more alto than tenor, and more smooth "r & b meets pop" than "rock shredder"), and acoustic guitar. Plus, it would be the MAIN mic and pre for 99% of all my tracking. So I wonder if the right mic/pre combo (at a lower price point than the Great River) might be:
1) A "cleaner" pre like the FMR RNP with a "warmer" mic like the CAD M-219, a tube mic like Studio Projects TB1 or T3, or AT4047
2) A "warmer" pre like a Joe Meek, ART, Universal Audio 610 Solo, or even an inexpensive Studio Projects VTB1 with variable tube warmth with a "cleaner" more open sounding mic like the AT4050
And no disrespect to Blindside (when it comes to a vocal mic, the word "smooth" always peeks my interest), but I can't find much of any info/reviews/opinions on the Sterling Audio ST77.
And regarding the Sure SM7b, well I think it would probably be a really nice fit for my voice, and it would be a no-brainer for a multi-mic locker. It's just probably not the right choice for the "99% use for vox + ac. gtr." that I need right now.
And Frets, my ears are probably just as "unsophisticated" as yours (which is maybe the main reason, other than price, that I'm hesitant to spring for the Great River), but I'm learning, and hopefully improving my recording technique, and my ears should improve with it. That being said, the ME-1NV would probably stay with me forever, and maybe the best mic + pre combo for me would be:
3) Great River ME-1NV + ANY mic
