【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.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. [Guitar sound hole cover] When you connect an electric guitar to an amplifier (guitar speaker) and play, it prevents excessive feedback and allows the sound to be picked up from the pickup (a device that converts string vibrations into electrical signals). For example, if the reverberating sound from a performance is picked up again, it can cause a squeal. These problems can be reduced.
