This is an early archtop Jazz guitar made by Arnold Hoyer. Suspected 1950s but could be early 1960s.
Hoyer is a large German guitar manufacturer who were well know for quality acoustic and jazz guitars. For its age, this guitar looks, sounds, and plays beautifully. There is some aging to the finish, which you can see from the photos. But it is fully functional with no structural issues. It tunes perfectly and holds strong tension well. It is ready to play and be enjoyed.
I’ve owned this guitar since 2008 and am absolutely in no rush to sell. It’s gotten me through many music exams and solo performances, but hasn’t had much use over the last 5 years. So if it can find its next loving home it can go.
BUT I have no idea what it’s worth!
