The TH30 head is both the cleanest and the highest gain amp Orange has ever made. The Clean channel delivers sparkling Fender-like tones, whilst the Dirty channel gives metal and beyond with the twist of only 3 knobs per channel. The TH30's Dirty Channel features a Gain, Shape and Master Volume. The shape control is an EQ control facilitating a variety of tones from classic rock through to scooped metal with all variations in between.
