The Orange Dual Terror DT30-H is a 30-watt twin channel all tube guitar amp head. It has dedicated Gain, Tone and Volume knobs for each channel, and a 3-position power switch that lets you cut the output power from 30 to 15 to 7 watts. The DT30-H comes with a padded gig bag carrying case. This amp is little in size, but don’t let that fool you, it has HUGE tone and plenty of volume! The Dual Terror is powered by four 12ax7 preamp tubes and four EL84 power tubes,which sound great when pushed.
