Here's my latest ukulele, #7. The top is white pine, and the back and sides are red oak. The neck is mahogany and the bridge/fretboard are walnut.
This isn't the loudest ukulele I've made, but it's the most balanced in terms of volume/tone/looks. The sound is focused and very clear.
Here's a video demo, excuse my playing, since i'm a usually bass player
