The knobs are exactly the same as the authentic Gibsons. I played a Gibson LP Standard at the store while testing out amps, and it had the same knobs, and pickguard for that matter. It's probably just a photo thing.
And actually, this guitar will sound the same as the Gibson, because those are authentic Gibson pickups in it too. I like it better than the Gibsons too. As I said, I tested out a Gibson LP standard ($2500 cdn) when I was amp testing, and I could not tell the difference between my guitar and the Gibson. I could tell before I got the pickups changed though. The thing is, my guitar feels a bit better than the Gibson did too. The frets are a little nicer in particular.
