Blackstar HT Club 50 MKIII 2-Ch 50-Watt Tube
Blackstar · amplifier
The Blackstar HT Club 50 MkIII is a 50-watt 2-channel EL34 tube guitar amplifier offering four voices from open clean headroom through tight high-gain saturation. Each channel offers two voices that shift gain level, tone stack behavior, and power amp damping characteristics. Blackstar's ISF control sweeps between American and British tonal signatures. The MkIII generation includes CabRig IR speaker simulation and USB-C audio output for direct recording and live front-of-house use. At 50 watts through EL34 power tubes it covers club and mid-venue stage volume with full tube dynamics. The combination of four voices, ISF, and CabRig DI output makes it one of the most versatile 50-watt tube platforms in the HT series.
