A combo amplifier is a type of guitar amplifier that combines both the amplifier and speaker into a single unit. This design makes it portable and convenient for musicians, especially those who perform live. Combo amps are popular among electric guitarists and can vary in size, power, and features, catering to different playing styles and environments. These amplifiers often include built-in effects, such as reverb or distortion, allowing players to shape their sound without needing additional equipment. Combo amplifiers are suitable for practice, recording, and live performances, making them a versatile choice for both beginners and experienced musicians.
