It's unusual for dye to not soak into the sides. Must be something on the wood. It's been postulated that the original reason for "burst" type finishes was because the end grain is so absorbent, it's almost impossible to dye a body without the edges being overly dark, so they started darkening them on purpose to have some control over presentation.
Since that's Ash, I'm not surprised it weighs 500 lbs. Also, Tele bodies are normally 1 3/4" thick, so you've got a little extra junk in the trunk there.
Next time, you might want to use grain filler to level the body out, then seal that before you dye it. It'll be a lot smoother and less splotchy.
Still, that should come out real pretty. I like the shade of blue, and graduating to black is a nice touch.
