I was expecting an outstanding instrument for the price. I have watched YouTube videos where this ukulele is played and was charmed by the sound of it. I had to have it.
My review is based on 2 ukuleles, since I have returned the first one and got a brand new replacement. Witch I am currently also returning for a refund!
So the problem is buzz when wound strings are played. The first ukulele I have received was not brand new and got signs of usage. At first I thought that Thomann has set it up for me. However right away started hearing the buzz when played. It seems that sometimes it comes from the frets, but most of the time from the saddle area. I have started looking and noticed scratches on the saddle. I lifted the wound strings and they audibly popped out from the grooves they have been embedded in. It looked like someone took a file and filed the saddle where the strings were. At first I thought that this is how Thomann has lowered the action. Also saddle and the nut had the wood like pattern and texture, so I had doubts that it was a GraphTech Nubone. So I have returned and received new one.
The new one was properly packed with all the flyers and other papers inside the box, that were missing from the previous one. I inspected the saddle and it was nice and smooth, although still looking a lot like wood. I have tuned it and played if for a week every day for ~30 mins before I started hearing the buzz again. Since the strings were not settled yet, I was not worried much. However it was getting worse every day. After two weeks strings have settled and I was now worried. I measured and noticed that fret 15 was much higher compared to surrounding ones, but also I noticed that wound strings have embedded into the saddle again.
By now I am pretty sure the saddle is not made of GraphTech Nubone as advertised, it took only two weeks for wound strings to embed into saddle. The frets are not even! They are also made from very soft material. Only after 2 weeks of playing I have started seeing flat spots on the most used frets below the wound strings.
This is the last Kala I have ever bought!
