A guitar amp head for the DG Series amplifiers gives you loads of power and all the fine performance of the DG amplifiers. Special Electronic Circuit Modeling (ECM) technology means you get the essence of old skool tube tone, while still being able to tap into the rich menu of incredible effects and complete digital signal processing. The digital section features internal 8 Channel Preset, Digital Reverb (Spring, Hall, Plate), Digital Tape Echo, and Speaker Simulator (LINE OUT). You can even download software to add tremolo, chorus, 80 new patches and MIDI effects control. Amp has been tested in great working condition, sorry no footswitch.
