In North Korea, I was figuring them for knock-offs or black market factory seconds that never had logos to begin with.
The first bass in the video is a Yamaha, and it looks like they might have altered the logo, or the resolution is poor. The second bass is an Ibanez with the logo removed.
The amps are Fender with the communist party tape over the logo. I don't recognize the speakers.
This is what they do in North Korea. I understand it's against the law to have products with logos from manufacturers from certain countries.
Of course, Kim il-whatever his name is knows that we'll recognized the products from the free world. It's about the pulling the wool over the citizens there.
