15W/7W Tube High-gain Guitar Head w/FX Loop. Plug into Orange's Dark Terror tube amp head and hang on. This amazing little amp pumps out up to 15 watts of incredible tones and excels at heavy, high-gain sounds. Plenty powerful for small gigs and rehearsals, the Dark Terror head also adapts well to studio use, as you can drop the wattage down to 7 watts for lower-volume saturation. Dial in an awesome gain range. Use the shape knob to tweak your tones to your liking. You even get a very cool tube-driven effects loop, so you can add your own effects and get even more killer tones out of this compact head. Crank up the volume knob and behold the sonic beast that is the Dark Terror.
