- Great for building a prototype of an electronic circuit, With referencing numbers printed on one side for easy reference of individual holes.
- The scale of the circuit can produce different sounds, while different keys correspond to different scales. The play of the electronic organ is to use the fingers to press different keys to produce different scales.
