Blackstar Series One Mk II 100w Head (Black)

The Series One 100 MK II head is a refined evolution of Blackstar's flagship high-gain amplifier line, designed for modern metal guitarists. Featuring over 30 circuit modifications, this amp delivers tight, clear, and defined high-gain tones without unwanted fizz. With 6 modes across 4 channels—ranging from Clean Warm to OD2—it provides a versatile sonic palette. The patented ISF (Infinite Shape Feature) allows for a range of tonal options, while the DPR (Dynamic Power Reduction) lets users scale the power down to 10 watts for flexible use in any environment.

The 100-watt dual-patent valve head includes 4x ECC83, 1x ECC82, and 4x 6L6 valves, delivering unmatched power and responsiveness. Built to last, the head features a 1.6mm seam welded steel chassis and plated-through double-sided PCBs for enhanced durability and mechanical integrity. The amp comes with a 4-way footswitch for easy channel control and integrates seamlessly into professional setups with MIDI switching capabilities.
