I haven't put a capacitor on the tone controls. The one I ordered wasn't in the box.
This makes me suspect that Hank wasn't really trying to do it different from every major rock star - he just doesn't have a capacitor available to use.
Could you salvage one from an old (defective) transistor radio? Preferably a really old one, that doesn't yet have SMD components. The Warmoth page will tell you what it looks like, if you find one with the correct value printed on it (.047uF) it should work. It will probably also be marked with its safe operating voltage but that will never be reached in this application.
