Notes
I had a thought last night that we could do away with the cabinet hinges and get a "cleaner" look but maybe slightly less ornate. Rather than have the strings threading though the cabinet hooks, why not drill holes through the box lid and neck wood? Then the string could be mounted by threading them through the bottom of the wood, up through the lid and across the fret board. More like a normal electric guitar? -- CM
