Description

Edit description

This is an item handmade by the president and workers at Maywa Denki's atelier, one by one, from the cutting of aluminum, circuit production, mechanism assembly, and painting.

It also comes standard with an "OTM link" that connects smartphones, so you can play with a variety of tones, effects, and autotune. It is a product with a vintage feel that has ample potential as a musical instrument.
