Guitar Heel
Demented Trick
It's absurd, but it's his guitar to mangle and his money to throw away. As long as he doesn't try to hide the damage when he inevitably sells it...He's going to freehand route a several thousand dollar guitar with a Dremel.
Let that sink in for a second.
He's killing all chances of selling that ax for any kind of profit, or even breaking even to "try something". By all means, swap the pickups, but routing it, not smart. It is his guitar (and money) though, so whatever.
