Generally, you need a special guitar adapter to connect your guitar to your Android phone or tablet. The adapter turns guitar sound into a data that can be read by your device.
Tonebridge compatible devices:
• iRig, iRig 2
• Ampkit Link
Note on USB devices: Tonebridge doesn't support USB connection devices like Behringer UCG102, Guitar Link, iRig UA, HD, HD 2 or iRig Pro. These devices use USB for connection, and Tonebridge currently supports only adaptors that use a headphone port for connection. Sorry for that, we're working hard to make USB connection possible.
