Alex,
This is just my opinion & many recording engineers disagree with me, but I personally think that mic choice is highly overrated. I do prefer large diagram dynamics over small ones, like SM7B sounds always better to me than sm57, but I could get there with almost any LDD. There are many factor to getting a big sound, but the most important one is dialing the amp right. I hope it helps, if you have any further questions I'll be glad to answer.
