Started by roughing up the case exterior with some sand paper and just applied a first coat of spray paint. I’d rather do powder coat but I don’t have the equipment or facility for that. But I’ve applied a light first coat and I’ll apply at least two more. And (boring) I’m using black paint. Still, it should look good in the end.
Also looking at using old Fender brown face knobs, of which I have a few. They are a cream color and will provide some contrast.
