MArk V 4x12 V30 recording mic placement

I think the title sums it up, haha. Currently I use speaker cab sims for my demos but, as we all know the real thing is the best option for tone so...

I can't find a good mic placement for killer metal tone. It always sounds honky and thin. I have a SM-57. Suggestions?

I am certainly no expert by any means. I've been recording direct for years, but always wanted to learn how to and use mics instead. I found this link that may help both of us:

This guy has more in the same series and he has a decent sense of humor, too.

Honky and thin would suggest your placement is too central on the speaker. Try moving the mic out towards the edge of the speaker. Also when dialling in your settings you need to have your ear where the mic is, because the amp will sound totally different from above. Generally when I record I need to dial the presence back quite a bit to tame the highs. I'd scoop the mids quite a bit too because the V is very mid voiced by default, that should "de honk" it some.

I did this shootout using the Mesa 4x14 Rec cab just as a reference for this discussion, single SM57: https://www.youtube.com/watch?v=qQNZu68kJR0
