Correct - this does have the wide plank neck.
Like I said though, this is exactly what I wanted as playing the thinner neck I kept slipping off the side. It's only a few mm's but personally it makes all the difference.
Cool dude. As long as you like it, that's all that matters.
For me, I wouldn't mind the slightly wider neck if the profile weren't so flat. I have an SG with a slightly wider-than-normal 70s neck, but it's extra beefiness on the backside makes it no problem.
