Blackstar's Series One 100 MK II head represents the pinnacle of high-gain amplification engineering, built specifically for the demands of contemporary metal guitarists. This flagship amplifier incorporates over 30 circuit modifications that produce exceptionally tight, clear, and defined high-gain tones whilst eliminating unwanted fizz. The amp's versatile architecture spans 6 modes across 4 channels, from Clean Warm through to OD2, providing an extensive sonic palette for any musical application.
At the heart of this 100-watt dual-patent valve head lies a premium tube complement featuring 4x ECC83, 1x ECC82, and 4x 6L6 valves, ensuring unmatched power and responsiveness. The patented ISF (Infinite Shape Feature) offers comprehensive tonal shaping capabilities, while the innovative DPR (Dynamic Power Reduction) technology allows power scaling down to 10 watts for versatile use across different environments and venues.
Construction quality remains uncompromising with a robust 1.6mm seam welded steel chassis and plated-through double-sided PCBs that guarantee enhanced durability and mechanical integrity. Professional integration is seamless thanks to MIDI switching capabilities, and the included 4-way footswitch provides convenient channel control for live performance applications.
