I had a feeling that this kit is simply a box filled random parts failed on quality control.
The neck and body had pre-drilled holes for alignment, but the neck was almost 4 mm off center. I had to cut the dowels, drill new holes and align the body and neck properly. The body is made with metal clamps and at some places the lining does not even touch the sides!
The fretboard is made from thermally modified wood and the material is very brittle. It was also badly warped. Probably that?s why it was uneven on the sides and almost 2 mm too narrow at the top. I had to use some leftover veneer from other projects to build up the missing part. However, since this is a finished fretboard, the frets are still 2 mm narrow at the nut.
The bridge is made from the same brittle wood. The holes for the strings are pre-drilled, but the strange spacing is uneven. The spacing two high strings is 3 mm(!) more then between the two low strings. The bridge location described in the instructions is completely wrong, you should measure it yourself properly, based on the scale length.
Conclusion - yes, it is possible to build a working ukulele from this kit, but you have to be familiar to the basics of guitar making. Maybe I simply got a wrong package, but the quality of mine was close to unacceptable. Thomann should either remove this kit from the shop, or design a better quality kit and raise the price with 5 euros or so. I bet this kit ends up in the trash bin in most of cases.
