all 3 definitely have their own sound...421 sounds best imo. the 57 really cuts off the bass low end wow.
I didnt care for the other two at all really, 421 was alone a lot in 1st place imo. 57 was really focused in the upper range and the plastic one seemed blurry and cheap...maybe more bass than the 57, yes, but the sound fakeD6 had that familiar blah lifeless tone.. imo....
sure a person can used anything but the 421 was quiet a bit better if you want that "studio" sound it seems to me.
I had a 421 with some Tascam package of Tascam mixer and the 8 track cassette rack mount deck..1989?...it always sounded really good, even today I think of it as crisp and as a good gear through my ears....of course I didnt hardly know anything about gear at all and had little interest in the specs etc. The internet and places like this didnt exist so it was a lot of weird shopping and unknown gear.
not long ago rabbit holed ...McCartney used the 421 for his first "solo" album....plugged into the reel to reel, I guess its a "all rounder" mic.?
great video as always, great sound and playback ... wow I was surprised at the difference of all 3.
