FERNANDES electric bass in sunburst color, with a built-in speaker for enjoyable playing. - Brand: FERNANDES - Model: Electric Bass - Color: Sunburst - Features: Built-in speaker The built-in speaker only produces noise. When connected externally, there is significant crackling. However, sound can be produced by adjusting the volume knob to a good position. I am a player and not a repair expert, but I feel that the internal circuitry is damaged, and the instrument itself is not in such a bad condition. This is for those who can send it for repair, those who can tinker with it themselves, or those who like the appearance and want to collect it. There is no case, so I will pack it with as much protection as possible for shipping.
