Dave Bellinger has long been known for his high end, innovative kalimba designs. This one matches a hot pickup, graphical buzzalizers, and generally smooth design and construction with the 15 traditional notes of the Mbira Nyunga Nyunga, aka the Karimba in F.
All of this makes the Bellinger F15 Nyunga a great instrument for looping. The lower row notes are the same notes as on the Student Karimba - meaning complete phrases of African songs can be played on the lower row notes. So, imagine playing a lower row song into the looper, and coming back and adding upper row notes to the second pass of the music.
Smooth, snooth, smooth.
