The first Polish keyboard for the tube! | Wind Instruments Service AkordBrass

We present to you, probably the first tuba keyboard fully made in Poland (at least in the last 50 years). Over the past year, we've been designing our proprietary brass keyboard. Made of the best materials and using precise tools, it can be a bold competition for the production of well-known companies. In this video, we will reveal the mystery of how we created it. The owner of the AkordBrass service, who designed it and supervised the production, tells about it.
