Ah, it's Harley Benton, they're a very cheap company, my friend ordered a bass amp from them and it sounds like there's distortion on it, even though there isnt, and he also ordered a Telecaster from them but it was made from plywood and the output jack kept falling out. They're a beginners company I'm pretty sure.
