I have a 1960s Hound Dog Taylor made by Kingston.

Check it out... http://i.imgur.com/jV3mq.jpg

I want to add a master volume to this guitar, but I can't figure it out.

Here's the schematic, which I just made. I couldn't find any diagrams for even a 4 pu guitar, let alone this particular guitar...

Any ideas would be hugely appreciated. This guitar has been driving me TOTALLY NUTS...

Instead of connecting the grey (ground) and orange (hot) wires to the tone pot, connect them to a volume pot. Then go from that to the tone. Can't think how it would be any different to wiring a regular master volume.
