No idea if you'd like the UU but it's a pretty different amp from the other Ubers. If you do get a chance to try one I'd be interested to know how you go.
I'm getting to like it more after spending more time fiddling. I actually wish I had waited to make that video because I've learned that Hair+, Deep high, Density low works better for most things.
But yeah it's a colder core tone, especially if you're fond of a Rev Blue's thick & rich thing. But I managed to get the Ch 1 Uber mode ballpark to a Blue with something like this:
Pres 3:00, Hair+
Depth max
Density 9:00
Ch1: B/M/T = 3:00, 2:30, 1:00
The upper mids still weren't quite right but overall not too far off.
