Boy, that tear-out is ugly. Don't suppose you have the chip from that, do you? I would make a tapered plug from maple with appropriate grain direction to fill the hole. Address the chip, stain the plug to match the neck, and French polish.
Do you know of any instructional posts that show this type of repair?I don't have the chip so I have to make one that will fit the damaged chip?The finish on the neck is pretty bad.should I leave it as is or refinish it?.Same for the resonator?
Pretty much like Greg says. Basically plug the hole with a tapered plug and replace the chipped out piece. To make it blend the best possible, you need to try and match the grain of the neck with the plug and chip. Finish touchup is not needed. Just polish out the wood plug to match the old neck.
Do you have a missing inlay?
