FREE BASS

Our laboratories can produce any model with "Free Bass". This can be an ideal tool to perform all the classical literature for accordion. Produced with keyboard or piano color, they are always cared meticulously for quietness of the mechanical parts, readiness of the keyboards, attention to materials, and manageability of the instrument.

我们的实验室可以将任何型号做成“自由低音”。这样整台琴更适合演奏手风琴的经典曲目，演出效果更理想。可以做键盘手风琴，也可以做巴扬手风琴。整台琴的设计就是为了让机械部件更加安静，键盘反应更敏捷，更专注于材料，整台乐器更加顺手。
