I liked cajon, but I never really liked the way you have to play on it. This instrument is how I like to play percussion plus cool sound of cajon!
The top (striking) surface is made from wood as well as two covers for the strings, while all other body is some kind of recycled material (100% eco). If you unscrew covers, you can easy access the strings and adjust tension using screws there (when I bought it was a bit unbalanced, had to adjust it).
I have to give 4 stars for quality, because I was able to scratch the front surface of a drum. Just by putting it against the wall with a rough surface (stone).
Also, be aware that you have to pay 1/3 price for the case if you want an original one from meinl.
