I don't know much about that luthier, but in general I think if collectible guitars are brought closer to their original state, rather than modifying, upgrading and replacing parts, then I think it should increase it's value. For example, some luthier's end up replacing the entire back or soundboard, but I would rather the original be maintained and skillfully repaired. Would like to hear what luthier Aaron Green has to say, seeing that he works with highly collectible guitars all the time.
