Just finished building a baritone uke. It's the third instrument I've built. The first two were guitaleles. The back, sides, and neck are maple, the top is spruce. The fretboard and bridge are bubinga. This was my first attempt at a color finish. It came out alright, but I like natural wood better. I did some further polishing after the pictures, it shines now. I'm going to try out true oil on the next one I think. This uke is more of a prototype and will be given to my father in the near future, although, this thing sounds amazing, I may not want to part with it until I build another one to replace it.
