yeah, he's overstating it. There's quality German gear and quality US gear. And both countries can produce crap too. Even with more emissions!
But that video he referred to is very telling.
But the Mini Rectifier is NOT the Mini Mark. And whenever the Rectifier may be too mushy, the Mark might actually be too tight. The thing is, it's easier to dial OUT the too-tightness on the Mark, than to dial in more tightness/less mush on the Mini Recto, outside the use of certain boost/drive pedals.
Having the Ironball *and* the Mark V:25 here at home, I'd say I'm quite qualified to point out any differences or similarities between them.
Similarities:
-both 2x EL84 amps
-both very lightweight and compact (14" wide, less than 16lbs)
-both 2 channels.
-both capable of (nice)clean and super high gain, as well as in between tones.
-both have reverb (with a reverb control on the back) and an fx-loop.
-both have speaker-emulated recording outputs
-both have a headphones output
-both can turn on an internal load for silent recording.
There are of course differences. And enough for me now to keep them both.
The Engl is easier to setup and easier for instant gratification if you haven't read the manual. The Mesa not so much.
The Mesa is louder, has more bells and whistles and 2 full featured channels (e.g. no shared EQ).
The Engl has a great power soak switch (20W, 5W, 1W, off), a Master volume knob, footswitchable reverb, Master volume boost (pre-set) and pre-gain Boost.
For a quick grab and go type of thing, I would slightly gravitate towards the Engl, as the Mesa's alot pickier about speaker cabs, guitars and has more tweaking possibilities, that can also make it harder to quickly setup.
Oh, and lemme throw a curveball that's sort of a mix between the Mini Recto and the Ironball, in terms of functionality:
