The finish is amazing! Wood tone, pattern and overall guitar design looks really well made. Even though it is an accoustic model, the concert body shape makes it somewhat smaller, lighter and more compact than, say, Jumbos or Dreadnoughts. However not much of sound is wasted because of a smaller size. Guitar has a mellow and comfy tone, with a bit more of bass and a natural "in-control" resonanse. Contrary to most other accoustic guitars, it also has a very defined and "strict" sound, giving you a lot of control for what you play. String action is low and lets you to play barre easily, despite being a 12 string model. Built-in tuner is sharp and fast, other electronics work like it should be working. Can tell nothing about the machines yet, I will see in the near future how it holds. So far, everything is sharp and nice.
Built quality is decent with almost no imperfections. The only set back in my particular model is a bit of space left in the back corner of neck-body joint, between neck and body (lack of glue or something). I will try to inquire Thomann if it might cause problems in the future.
