That LP is looking really good despite the flaw in the finish, I'd call it custom relicing, I love how the wood grain shows through the body finish, you should record a demo so we can hear how it sounds.
With regards to noise while using high-gain sounds, if it's any consolation, my HotRod Strat gets a bit noisy at high-gain settings too, even though I have put copper shielding tape in the routing, I've even put copper shielding tape in the Tonerider Rocksong Bridge Humbucker pickup too.
