I appreciate your perspective, and you need to appreciate the perspective of someone who might be interested in shelling out a lot of money for an Alembic bass. To me, there's nothing philosophical about it. Just because the instrument doesn't hum, that doesn't mean it is correct or that it sounds the way an Alembic is supposed to sound. In philosophical terms, I believe a repair involves setting something back the way it is supposed to be. Your perspective seems to be that a repair simply involves making a broken thing work.
In any case, the modification is disclosed here, and you probably should provide pictures of the insides of the electronics cavity as well. Alembic fans are generally pretty wary of any tinkering done in there outside of the factory. An issue like this that isn't fully understood would knock at least $1000 off the value of the instrument to me. Others may not care or may place a different value on it. Understanding what was done, if it is right or not, and what it would take to set it right would make a difference.
By the way, that's an interesting neck wood recipe. Looks like maybe two walnut stringers on the outsides. The center one could be purpleheart, vermillion, or mahogany based on the color. I just can't tell, especially with the way the older finishes color as they age. Does the original paperwork tell you what the neck woods are?
