This is a 4-octave Yamaha marimba. It is discontinued and no longer sold. It is a used item, so there are some minor scratches on the legs, but this does not affect the performance. If I had to mention something, it sometimes creaks when you hit the low notes. Other than that, there are no cracks in the bars, so it's perfectly fine for practice. I am busy, so it may take some time to hand it over. I will discount the price by about 10,000 yen for those who can trade directly.
