Blackstar HT Stage 100 MK III Head
Blackstar · amplifier
The Blackstar HT Stage 100 MK III Head is a 100-watt EL34 tube guitar amplifier head offering two channels with four voices spanning pristine clean warmth through brutal high-gain saturation. The MK III update adds Blackstar's CabRig IR speaker simulation system, USB-C audio output, and built-in reverb, transforming the Stage 100 into a fully self-contained recording and live performance platform. Blackstar's ISF control adjusts the tone stack between American and British character. At 100 watts through four EL34 power tubes it delivers full authority for the largest stage environments while the CabRig DI output eliminates the need for stage microphones in recording and live applications.
