Thats a good price, especiay since it has the included footswitch, which is hard as tits to find. But in my experience, a pedal was needed. Kirk Windstein and Dimebag also used some help (Kirk used a Metal Zone as an overdrive for the gain channel and Dimebag used a grahic eq pedal and a rackmounted parametric eq..)
My favorite budget metal head is the Ibby TBX150H. Can be found used pretty cheap. Some others are the Crate Gx130c and Crate Excallibur. Ive seen the GX900s and GX2200s go really cheap and they can get really heavy. Worlds better than modern Crate stuff.
