This is a Marshall MG10CD, a small amplifier. Despite its small size, the sound is pure Marshall! When distorted, the rock sound will envelop you. It has enough power that you can't crank it up all the way at home. It works perfectly, with no crackling or noise. Thank you. - Model Name: MG10CD - Features: Emulated Headphone, Line Out - Controls: Clean, Overdrive, Tone, Volume, Gain, Contour Thank you for looking.
