I've got a MIM Strat that I'm thinking about dropping a set of P-Rails into, but the neck slot is only routed for a single. How difficult would it be to rout it out for a humbucker? I'm not concerned with how it looks, as it's going to be covered by a pickguard, and since it's an MIM, it's not as though it has a huge resale value that I'll be destroying.
What type of tools are necessary? I've got a dremmel and a couple of drills, and can go buy the appropriate attachments for those.
