I have a Johnny Marvin Professional Tenor Ukulele that I found in our attic. When I opened the case I was shocked of how great the condition is! There's not a scratch on it. Underneath the ukulele were original Hawaiian strings with a pitch pipe. (The ukulele has been restrung since) I have no knowledge on ukuleles and was looking to learn more about it and how much it's worth. I can post pictures later see if anyone can help me out with this.
