Quite a few years ago I bought a banjo type uke that had a wooden tone ring made up of two types of wood glued together forming the circle. It has a resonator and a three piece neck. Apparently a lot of work went into making the thing, however it has a lousy sound and if it had strings when I bought it I probably would have saved my money. Of course seven bucks wasn't a bad price.When I started playing the uke there were no nylon strings. I still prefer the sound of the gut strings or the nylon strings that simulate the gut string.
