Guitar combo with 5W power. Ideal for powering an electric guitar, but also other instruments such as a drum machine and keyboards. Controls include a master volume and tone control to determine the character of the sound, and an On/Off/Overdrive switch to set clean or distorted sound. The headphone output is provided by a 1/4" stereo jack connector and provides the possibility of silent exercise. This combo works with the included mains adapter or with batteries (not included), which allows you to use it outdoors or in areas without an electrical outlet.
