The Joyo Top-GT amplifier is a small and portable device that combines a bluetooth speaker with a guitar amplifier. It's perfect for practicing your guitar skills (it has Voice, Drive and Tone knobs) and can also be used as a standard portable speaker.

Joyo Top-GT can be connected to any mobile device and works with most applications. The included 3.5mm connection cable allows you to connect the Top-GT to your smartphone and enjoy the flexibility of amp and effects simulation apps. The guitar, on the other hand, is connected using a standard guitar cable.

As a Top-GT speaker, it has the ability to connect via Bluetooth 4.0 or AUX input. In addition to the built-in speakers, you can easily use headphones with it. It has a built-in battery (2.5 hours to fully charge) and can even be used while it's charging, so you won't have to interrupt your session!
