Arrived in tune, plays very smoothly.
After switching to a rather esoteric tuning, I managed to track this into a section of a technical deathmetal song.
If I'm the first person do play a marimbula in such a context, I'll take as much blame as credit; you're all welcome and I'm not sorry.
If you buy a factory-made marimbula, this is the one you want. I encourage anyone with even a passing interest in the instrument to give Schlagwerk more reasons to keep producing these, despite the limited number of players who know what to do with one. The learning curve is not steep, just listen to some changui and the traditional patterns become available.
