What is the value of an ovation preacher guitar?

If it's in very good to mint condition and includes original hard shell case, you should get at least $1000 for it. The preacher was made in Connecticut between 1975-82. It's very solid, heavy and it has a killer vintage humbucker tone. It was Ovation's version of the Gibson SG. In my opinion, better than the SG. It has active pickups that will make it scream some killer 70s, 80s hard rock solos. I love mine.
