Amp Head 

A Guitar Amp which only consists of the Preamplifier and Power Amplifier stages. Speakers are purchased in a separate unit called a Speaker Cabinet. Amp Heads, or "Heads" are usually less expensive than an equivalent Combo Amp, as they do not have speakers, but they are far more durable and flexible.
