I’d say for a camera in the room recording that sounds as good as any other throwaway portable practice amp. Nothing is going to sound great at that size. Even everyone’s beloved Yamaha micro amps sounded ass, but really good for a desktop amp.Hm, in Cordy's video the thing sounds pretty bad to me. Might be the camera mic, though.
For a practice amp, and from Mooer of all people, it sounds pretty amazing on every demo I've seen so far.
I need to find out if it has a flat setting but, for the price, this might very well be it for me.
In that video it sounds nice, but I'd guess it's the line out used. If the onboard speakers are able to halfway transport that sound, it might be fine.
Phone-only editing however sucks quite a bit.
