I really enjoy playing guitar and looking forward to free time to practice. But carrying all your staff is very difficult - pedalboard and amplifier are very heavy. Heavy, like my favorite music.
Nevertheless, I often want to play guitar. I tried to look for such software for phones. Found only for iOS, but due to low incomes I can't afford to buy an iPhone. So I tried to find something similar for android. I have not found. And today I came across this video.
I don't know this language, but it's easy to guess the purpose of these actions. First, andrig is installed on android device. Next, through the usb adapter to the device android connects an external sound card. This sound card can be bought for 1-2 bucks on Alibaba. A guitar is connected to the input. On the output there is a loudspeaker. Any loudspeaker is suitable.
This is a very good idea, because it allows you to carry your entire staff in a small bag.
