Those mics are like swiss army knife, you could record anything it used with the correct placement and preamps
They are great for overheads (drums) for accoustic instruments like guitars etc..

This has to be the first time I've ever encountered someone who has three 414's - which is one of the most-often used mics in the last 40 years of recording history - and doesn't know what to do with them. :confused:

The 414 is a great mic, and can be used on virtually everything.

Because of its patterns, they can be paired together and used in XY, M-S, Blumlien arrays. Sensitivity is exceptional, as is the bandwidth and SPL.

You can use them on:

Vocals
OH Drum Mics
Acoustic Guitar ( or any acoustic instrument, such as Violin, Cello, Mandolin, Upright Bass, etc)
Guitar Amps
String Sections
Vocal Sections
Piano
Bass Cabinets
Leslie Cabinets
Drums - snare, kick, toms, hh
Timpani
Brass

The list is endless. It's probably a lot easier to list the things that you can't use them on... wait... I'm thinking... Nah. I got nothin'. They're great for everything.
(I guess if I had to pick, I'd say to avoid using them to mic a chainsaw... and not because it wouldn't make the chainsaw sound good, but because you'd probably want to avoid getting wood shavings and sap all over the mic. )

As long as you pair them with good preamps, ( the Great River you have would be perfect, although of course, you can only use as many channels as your pre as) and know how to place them, and know about mic technique in general, they are fantastic mics to have and use.

Not that there's anything wrong with your SM7... but they are two distinctly different mic models and types.

If you haven't yet tried one of those 414's through your pre and on vocals, well....let's just say that you should. ;)

I either go for the SM7B or my AT4050 I'm trying to figure out if I should sell them or if there is some other practical use for them. Could they be used to record an upright bass?

They are good on everything, and great on some things. The sm57 of LDCs!!!!!!

The C414 is my dream LDC. When I step up from the cheap mics I can afford right now, I'm not gonna play around. Going straight for one of those.

c414's suck. you should give them to meeeeeeee!

Kurt's right. And if you have one that ends with "EB", those are the worst of the bunch. :whistle: I can give it a loving home away from all those other mics you might have.
