I think the topic of a battery powered amp came up again recently someplace. I forget where so I’ll just put this here. I haven’t heard it yet, but this has the potential to be as good as a 12" bass cabinet. Because it’s full range, it would be possible to put any cab sim in front of it and let it morph into different bass cabinets. (Assuming its frequency range is pretty flat.)
Just released at NAMM this week . . .
