The HT-5RS mini stack combines the HT-5RH head with two 1×12 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.
