Featuring a dual EL34 vacuum tube preamp, two 12" Celestion speakers, and three channels with separate EQ for each channel, the Blackstar HT Stage 60 2x12 Combo marries classic tube-driven sound with the company's modern components and construction. Built with Blackstar's Infinite Shape Feature (ISF) for an even wider spread of overdriven and clean tones, this amp brings serious muscle at an attainable price.
