Huge performance kalimba with low, deep sound and good sustain. Top quality, single, handmade instrument. While it has 20 lamellas, 12 of them are standard, producing loud, colorful sound and 8 are sympathetic, working for creating additional resonance. They can be played too but this is less convenient than side keys. Every lamella is forged by hand and tuned to custom author's African scale. Two types of shakers are present - rhythmic for bass notes and light for gentle background buzzing. It is powerful and inspiring kalimba.
