This is a late 70's I believe Alvarez F-style mandolin. I believe it is an A-700 from the research I have done. I will tell you this. It is an absolutely beautiful piece. Projects much better than the Loar I have and has a MUCH better tone. Killer mandolin for sure. Has a Pickup installed. Pickguard was removed forever ago. Has some light pick rash near the F hole. Has had a few tuner buttons replaced. I would probably get a new set of replacement buttons were I to keep it. All in all a VERY nice instrument. Has a new Superior case. Still has keys. Great mandolin. Great tone. Great playability. Great case. What more could you want? Make me an offer.
