Hi, welcome to the forum and to Guild ownership. You are off to a good start!I am unclear if you are trying to appraise your guitar for a general value, or actually intend to sell it. The value of Guilds, especially acoustics, is kinda "all over the road." Any Guild is a textbook example of "it's worth what someone will pay" and yours falls directly in that category, on many levels. You can check completed listings on eBay to see what they have sold for. The one you have would do good in a guitar shop where someone can try it and fall in love...selling online works for some, but is not for everyone, and not for every guitar. When you brought it to Guitar Center, did you ask them how much they would pay you for it? Considering what you've paid, If you are not keeping the guitar that is definitely a nice option to have (hurry up if so, in case they go bankrupt!). Guitar Center is a great place to sell a guitar, but probably not the place for major repairs. Yours looks good though, I'd be optimistic and hope a qualified luthier will tell you it does not need a neck reset at this time. But as other have stated, either way- this is a home run! Congrats!
