Harmonica test equipment - HMT-2

Harmonica testing equipment.

Now you can “play” a harmonica and listen to the sound of a blues harp or a chromatic harmonica.
With this test device, you don’t need to put the harmonica to your mouth to hear it play, avoiding the risk of infection and contamination from other people.
The test unit has several functions: it can play multiple notes at the same time or only a single note at a time.
