Did another clip; this time, have the amp biased better (it was rather cold in that first clip..my bad) and I switch back and forth between fixed and cathode bias.

Both the cathode biased and the fixed biased sound great to me. The cathode biased sounds somewhat smoother to me and the fixed biased seemed a little more focused in articulating the notes.

Really liked the amp tone & enjoyed the jazzy/blues stuff you played at the start of the video. Nice!

With respect, 10thtx

Thanks man. Yeah, they're both good and useful. The biggest difference seems to be in the attack of each note/chord. In fixed bias, the attack is faster, "harder" and more precise. In cathode bias, it's not as hard/stiff (boy these are some funny, double-entendre kinda adjectives I'm coming up with, LOL, but they work). I think I prefer cathode bias a bit more for bluesy kind of stuff and fixed bias more for rock type tones/playing. But it's nice having the choice.

I will also say that the amp is definitely louder in fixed bias mode. This is a double edged sword...

Midnight blue is one of my favorites .
If I may ask, what values did you use for cathode bias? 250 ohm 10w? 25uf ?

Yeah, that whole LP is priceless!! What a classic! As a son of Detroit and a WSU alumnus, I got a lotta love for Kenny Burrell.
