Yeah different power amp designs have a BIG impact.
I think the first Uebers were running hotter in the power stage, which makes them a bit more chewy and organic to the blue revs. Not sure how the Duo Jet compares in that perspective.
"Downer" for the classic is that it's lacking some of the switches of the 101B, whereas the 20th offers that classic vibe with improved signal quality (highest specs caps and stuff) but also all the switches like gain structure etc.
been thinking about all this. there is a 2nd hand classic for sale near me, and a 101B.
its a lot of cash, but i think overall, now i've gone out and played my Uber kranked up, it does exactly what i want, and im happy with the sound now im used to dialling it in.
still LOVE my avenger for all kinds of reasons.
any idea what the Uber cameron mods are?
