Fender Bassman 30 is a compact and reliable amplifier that combines power, control, and versatility in one package. It is equipped with two inputs, allowing you to connect two instruments simultaneously. The Volume knob controls the overall volume, while the Limiter LED indicates when the limiter is engaged to prevent distortion. The Master knob provides additional control over the overall volume, and the Treble, Middle, and Bass knobs allow you to shape the tone of your sound.
