When buying a guitar, buy an acoustic acoustic guitar of about 2000, and then have an external pickup.
In this way, the ideal effect can be achieved whether the power supply is connected or not.
If you are in Tianjin, I suggest you go to Nankai District Teana Guitar Training, where guitars are well debugged and sold.
I first learned guitar from Mr. Ma, and then bought a guitar with the help of Mr. Ma. Students who play guitar around also say that it is better than buying an electric box guitar directly.
