The HT-5RS mini stack combines the HT-5RH head with two 1x12 Blackstar voiced speaker cabinets. The innovative Blackstar HT-5H guitar amp head offers unbelievable tube sound in a compact format. Using the dual-triode 12BH7 wired in a push-pull circuit, you get the crunch and break-up characteristics of a traditional 100-watt amp at a much lower volume. This design creates a sound rich in tube harmonics and compression even at the lowest levels.The HT-5H"s three-band EQ is augmented by the Infinite Shape Feature (ISF), which provides infinite new tone-shaping control. The emulated speaker output/headphone output offers both 1x12" and 4x12" settings - great for recording or practice.
