Tried the drill and chisel method and it worked pretty well. I'll clean it up a bit over the weekend and hopefully get the pickguard holes drilled, pickups wired up (I've never done it before so I'm a little worried about getting it right) and it'll be good to go! Here's an idea of what it'll look like when it's all done.

Also, I'm thinking about putting a design on the truss rod cover. I'm a huge comic fan so I was wanting to put a drawing of groot from guardians of the galaxy to match the natural wood theme of the bass. We will see how ambitious I am once I'm done with the hard stuff!
