Wow, check out some of these really cool DIY Thumb Pianos!
Sometimes an instrument you know can become something else altogether. Bob Collier has been constructing his own thumb pianos, adding amplification, effects, self-sampling features, and novel cases involving recycled camera bodies and faux fur. As Bob says, “Sometimes the crudest and roughest looking kalimbas can sound surprisingly good especially with the right context of fx and amplification.”
I find kalimbas beautiful and delicate to begin with.
