You mean like I did in this post? I've got several pictures there, although now I no longer have either of those guitars and the amp has gone to my son. Still have the bass, though.

If you mean post a picture of the control cavity, I don't think it will help you much. I have it in front of me and it is hard to follow. the pots are small and easily obscured by the wires.

Does the hum go away when you touch the strings? I'd check to make sure everything was grounded properly first.
