One warning I want to offer about this video. They are using the DI out for all of the recordings. You’re only getting the sound of the preamp. Listening live would be significantly different because of different speaker sizes, combinations, and designs.
Having said that, I like this video. There is a lot to learn from it. I wish more gear review videos did away with all the talking and stuck with the topic of the video like they did here.
Ah, thanks! Now, it does make a bit more sense (I guess) why they looked at a little 1x12 next to a larger 2x12 or 4x10 combo…
These guys actually have a lot of videos where there is zero talking 
Dought! My bad @joergkutter.
I had missed the little blurb at the beginning that says, “The signal you hear is 50% DI and 50% microfon.” I find that surprising. All the different speakers didn’t seem to make any real difference. Weird.
You’re right. That channel has some pretty great videos.
I like the part where they compare the amps with a live drummer and different mics. I’m a Fender guy but I do like the output of the Markbass in this video. Altho I think you need a little bit more watt when playing with a drummer?
