I recently commented on vocal mics in another post, but I think I'd say the same thing here.
The mics you are looking at sell roughly for about $400 or so. That's a pretty good place to start for vocals, but you should NEVER skimp on a vocal mic, especially if you do not want to do too much surgical EQ later on down the chain. In the studio we have a couple of "go to" mics. Obviously the U87 is THE standard, but quite expensive. I always recommend looking at the Neumann TLM 103. Without getting too technically deep, it is a watered down version of the U87. New they are about $1,100, so try to find on used. I promise, you will not be sorry. The other plus is that if you record acoustic guitars, you'll never use anything else. I actually like it better than the U87 on acoustics as it is a tad darker sounding to my taste and I usually reach for it over the U87, unless the acoustic guitar is pretty dead sounding.
For guitars, especially crunch and overdriven source material, the Royer 121 was a game changer for me. The ribbon sound is warm, organic, and still BRUTAL if you want it to be. I am fortunate to have a matched pair in the studio and we use them live too. Every FOH guy that mixes us is wildly happy to see us bust out with 121's instead of the usual 57's or 421's. Actual FOH guy quotes include: "wow, these guys actually know about audio" , "Oh thank God...this is going to be easy", " Holy sh!T....you guys got two of THOSE...NICE!" :lol:
I used to use a combination of a 421/57, 414/421 and I had to fight to get what I wanted. Then there were the phasing issues if they were too far apart. I've said before in other posts that I must be the only IDIOT in all of "guitardom" that never dug the sound of a single 57.
After I got the matched pair of 121's I've never looked back and I get an amazing sound quickly.
This is just a starting point, you need to consider the mic pre...this stage of the chain can color you sound as much as you plugging your guitar into a different amp. Getting the right combination of mic/pre is the silver bullet!
Let me know if you want me to ramble on about mic pres! :lol:
Best of luck to you my friend!
