That bump at 6K on the 57 is as if designed to bring out sibilance in vocals lol. I got a 57 recently and tried it on my guitar amp, but it sounds crappy. (The piezo on my guitar makes high frequencies unattractive, and the 57 compounds that and makes them ugly.)
Okay, I'm going to listen four times.
1 iPad: Good separation, balance and sound. Is that you singing? You sound younger than previous stuff. You taking viagra? Or is it just a matter of you singing differently on different tunes?
2 Earbuds: Immediately better sound, but a different frequency response - the guitar comes out nicely. Ordinarily, I'd want the vocal a taste louder in relation to the guitar, but the doubled vocal makes it all okay. Lesson learned. Drums could be louder.
3 Mixcube: A third frequency response - that backing guitar comes through more distinctly, and it's really nice. You want to make that happen in the real mix through monitors?
4 Monitors (KRK VXT8s): Wow! So big, and suddenly I can hear the lower end! Okay, that's an issue - I *didn't* hear much kick or bass at all on any of the previous three listens. Can you get the bass and kick heard on earbuds without turning them up? How would you even do that? Create a submix and boost 700 Hz for it?
Nice tune, Mark. Good work.
