Built-in 4 Effects: This portable guitar amplifier is suitable for electric guitars and features four built-in effects—clean, distortion, overdrive, and reverb—to support your daily practice needs. Compact and Portable: This mini guitar amplifier is an ideal companion for travel or on-the-go practice. Its small size makes it easy to carry in a backpack or luggage. Despite its compact design, it delivers sufficient volume for practice with a 5W speaker. Plug and Play: Equipped with a 6.35mm input jack, the amplifier offers convenient plug-and-play functionality without the hassle of complicated wiring. The design allows it to be easily attached to your guitar for immediate use, enabling you to practice anytime and anywhere. Bluetooth Function: This mini amplifier includes Bluetooth o connectivity, allowing you to stream music from your smartphone or other Bluetooth-enabled devices. Play along with your favorite tracks as accompaniment. Note: This device does not support Bluetooth headphones or Bluetooth speakers. Rechargeable Design: The amplifier features a built-in rechargeable battery that provides approximately 6 hours of usage when fully charged. This eliminates the need for frequent battery replacements and allows for greater flexibility during outdoor use. We recommend using a 5V 2A charger. Avoid using chargers with voltage exceeding 5V, as they may damage the device or cause safety issues. Note: Due to variations in product batches, the appearance may differ slightly. These differences do not affect performance.
