I like using the guitar to get the gain / drive matched up between the DUT and AxeFx, but would there any advantage to switching to pink noise for the final match / refinement?
Excellent video, Cliff!
Amp In. You want to capture the whole amp, not just its power amp.
Your Cascade Fathead should play nicely with other mics if pulled back 4-8" from the grill.
If you want to try a reference mic the Behringer ECM8000 (approx $55) is surprisingly good, not quite as flat and a little more aggressive than an Earthworks but for the price it's outstanding (you'll probably get more coloration from your mic pre than the difference between an Earthworks and the ECM8000).
