Taras, comparing all your clips, the biggest difference I heard was between the two mics. I was surprised how little difference I heard between positions 1 and 3. I would expect it to be massive, but it really wasn't. Maybe if I used Amplitude I would start hearing subtle differences that weren't evident on first listen. At the tail end of each clip you had that palm muted part. If I were miking an amp, I would zoom right in on that section when choosing a mic position. If I were looking for clear, sharp, and percussive attack, I'd move the mic inward toward the dust cap. If I wanted fatter and softer, I'd move it out toward the edge. I'd expect to hear a big difference. Of the two mic options in those clips, I preferred the Royer.
