Cascha Bass Ukulele Set

There's a lot on this bass that should be much better than the one I got. First off right out the box (after extensive tuning) the bass had a lot of fret buzz, especially on the lower E string and the lower register. Furthermore, when I finally got batteries for it the tuner didn't work at all and only occasionally showed B or G briefly. And when I finally tried plugging in into my sound card there was no sound at all, the pickup didn't work whatsoever. But if I look away from the fret buzz I think it's a great feeling instrument that sounds very good and so much fun to play and I feel like the rest of the instrument is very well built. But obviously something is very wrong with the electronics and I must therefore send it back.
