HB-4S with a few improvements. And a lot of chemical ebonising. A lot.

For the pickup surrounds, tape a piece of sandpaper to the top of the body, around where the pickups will go, and use the arch of the top to shape the base of the surrounds.

That is such a good idea, and a far better way to approach the job than the way I chose.

Here's my approach.

1. Take the shape from the front of the guitar using a flexible curve.
2. Scan the curve.
3. Convert the scanned image to a simplified, closed SVG shape in Inkscape.
4. Import the SVG into Blender and create a 3D model of the pickup.
5. Use BlenderCAM to turn the model into a cut pattern for my mill.
6. Get halfway through the cut job and discover that the mill is slipping on the Y axis.

The mill is getting some attention and should be ready to cut again sometime during the week.

Maybe I should do the sandpaper idea instead... the advantage of using the mill is that I can cut as many pickup surrounds as I want. I'm also laying out a generic pattern for cutting normal humbucker surrounds for some of my other guitars.

I've attached a photo of my little 3020 mill. The working area is roughly A4 sized. I mostly use it to cut faceplates for my valve amps.
