Power @ 4 ohms: 25W
With a more typical 8 ohm cab, according to the video it's just 12.5W.
That's super underpowered for a Class D poweramp. Yeah it will probably make loud enough noise, but won't handle any transients anything like an equivalent power tube amp.
Watching that video, at first I was "ok, I can see those 4 knobs being able to do some work, even if it's a bit weird"...but then they get to the screen. It's not a touchscreen and is this poorly laid out thing you have to control entirely with one knob and its switch. And the graphics look like crap.
There's so many way better rigs you can build with that money. I could buy a freakin' BluGuitar Amp 1 ME + Fractal VP4 for (slightly) less money.
I like this on an idea level, a little clean looking pedalboard you plug into a cab or PA. I think the execution is just completely wrong.
