The same F-15 nyunga nyunga instrument, with an electronic pickup (PU) installed.
A new model of the Hugh Tracey African Tuned Karimba, in F, with 15 notes (ie, with the mbira nyunga nyunga note layout as opposed to the 17 note karimba layout), mounted on an alto box for a louder sound and more expression. This one has an electronic pickup. The notes on this one are thought to represent the original mbira created some 1300 years ago in southern Africa.
We don’t have sound clips of the Box F-15 Karimba + PU, please listen to these sound clips of the acoustic Box F-15 Karimba:
This matches the tuning, layout, and key of the mbira nyunga nyunga precisely.
