【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. A special model for harmonica players who are always trying new possibilities! There are holes on both sides of the cover, making it easier to hear overdraws and overblows, allowing you to enjoy thick tones. If you feel that there are limits to how you can play or the tones you can express with a 10-hole harmonica, try this harmonica. It is also recommended for those who are stuck due to overdraw or overbrow to get a feel for it! By plugging each sound hole on each side of the cover, you can easily play overdraw and overbrow, and get a thick, beautiful, loud sound. The original sound of the reed reverberates directly from the sound hole, so if you apply hand vibrato with your hands or cover the entire harmonica, you can control the tone more freely than ever before, such as singing tones or bluesy tones.
