Hey Jay! First of all, thanks for taking the time to answer our questions!
What is your approach to getting BIG rock guitar sounds? Do you favor any particular mics in comination with each other? Thanks!
It really depends on the way the amp sounds. As a general rule you could usually start with a 57, 421 and something like a Sony C-38. I'll first solo each of the mics to see what they sound like, and then just experiment with different levels of each, in combination with one another. Sometimes a U-47 or 87 a few feet back can add some body. For a solo guitar, adding a condenser mic (with a lot of compression) across the room and facing away from the amp can give some nice size to your sound.
