Hugh Tracey Chromatic Celeste Treble
This is an option for playing chromatic with medium or smaller hands.
The board is 3/4 inch thick and this is the kalimba that Sharon plays in the YouTube video. This one is definitely better for small hands - meaning many women and also many men (ie, not just children).
Each of these kalimbas come with the built in pickup.
We don't yet have a photo of the Celeste Chromatic Treble, but we will have one up when these kalimbas come in from Africa.
