Thanks my man!
I've considered adding a room mic, but not to layer in conjunction with the SM57. I'm more or less trying to give the most simple representation of my amps, which is why I use a mic and speaker everyone is generally familiar with. Makes it easier to compare with my other videos as a point of reference.
The room mic would be cool as it's own standalone thing that I cut to in certain situations just to show the in room sound.
