The Powertone II amp head offers three channels and two separate Master Volumes for setting two different volume levels, Rhythm and Solo, on each channel. The Clean channel offers luscious clean tones, rich open and well defined. The Gain channel has 4 tube stages and its improved dynamics and pressure make this channel the best chords-channel for every blues and rock style.

The Ultra-Gain channel goes further than many people think possible. Its 5 tube stages bring you high gain and harmonically rich and singing lead tone while still having excellent chord definition.

The completely redesigned 120-Watt power amp produces an incredible amount of push in the Low End, has more headroom and greater transparency. The Powertone II also offers 3 Speaker Damping levels: High, Low and Ultra Low. The Ultra Low damping makes the amp sound incredibly open and powerful. With all these features the Powertone II amp head will give you a superb sound for every music style on every volume level, from not-to-loud small club level to a feel-it-in-your-stomach grand stage level.

The Powertone II's simple and intuitive user interface allows you to easily create, control and refine all the tones you've ever desired. From a sparkling, open and very detailed clean tone through a rough and grungy rock tone to a lead tone with an almost unlimited amount of gain, it's all there.
