This rugged amp head combines outstanding features with serious clean and distorted sounds. An easy to operate DSP section lets you dial in a variety of digital effects including reverbs, delays, octave and wah-wahs - with a separate level control. The supplied 3-button footswitch allows you to select between the three channels and turn the DSP on and off by "remote control." The electronic tuner lets you get tuned and stay in tune any time the amplifier is on.
