Blackstar · amplifier
The Blackstar HT Stage 100H MkIII is a 100-watt EL34 tube guitar amplifier head offering two channels with four voices spanning warm clean tones through brutal high-gain saturation. The MkIII update adds CabRig IR speaker simulation with hundreds of mic and cabinet combinations selectable from a front-panel switch, plus USB-C audio output for direct DAW integration. Blackstar's ISF control sweeps between American and British tonal characters. At 100 watts through four EL34 power tubes it delivers full-stage authority for professional touring and large venue use. The CabRig addition transforms the Stage 100H MkIII into a fully self-contained stage and recording platform.
