don’t know if it’s your cab or 6l6s but you get a fuzzy top end almost recto-ish that I don’t get with my el34s which is cool, on top of a modern hifi SLO-ish ‘present’ bass and a clanky and (i refer to it as) slutty midrange.
there’s this psycho-acoustic thing with big amps that ime once you experience you can then notice even via phone clips.
my Wiz and previous SLO and Gower SE modded
Marshall had that too and I get it whilst hearing your vid on my phone.
i can also tell how unforgiving it must feel under the fingers just by hearing how you got it dialed in and crossreferencing my experience. but gaud dayumn it tracks like it’s on rails.
I got MC1 at a time when I was practicing a solo for an upcoming track using my XTC 101b so my chops were up.
I did a trial take with the Wiz and immediately sold the xtc bc of the MC's added articulation on fast passages up the board without thinning out.
Lately I haven’t played as much bc of kids and every time I try to solo with the MC1 I wish I had the xtc lol. cracking amp that too but too much character to work with
