I think ol’ Laura’s regrets encompasses all you’ve mentioned. But what the heck, I’m thinking of a 20 year old guitar purchased new, fawned over for a few weeks, put back in the case and forgotten for years and years. No maintenance like that on a National or Martin/Gibson, etc., it may be worth the neck reset and work to bring it up to speed...Norman? Not so much.
Hey, may be pristine though. I can be an optimist! Optimism doesn’t have to be realistic! Laura, hows the neck angle? Frets poke you? Binding, if any, still flush?
Y’see, musical instruments that DO have value need to be maintained, air too dry, well, 20 years of that takes its toll, add to the story the string tension and neglect over years of wet/dry, and a lot of times those old pristine instruments have some issues a simple setup won’t address. But maybe not!
