Blackstar Series One 100 MK II Head

The Blackstar Series One 100 MK II is a 100-watt all-tube guitar amplifier head representing the flagship of Blackstar's modern high-performance amplifier range. Designed for demanding players, it delivers uncompromising high-gain performance, exceptional dynamics and professional flexibility for the stage and studio. Combining classic valve character with advanced technology, it is perfectly suited for modern rock, hard rock and metal.

Powered by 4 × ECC83 preamp valves, 1 × ECC82, and 4 × 6L6 power valves, the Series One 100 MK II produces tight low-end response, rich midrange and articulate highs. Its four fully footswitchable channels provide exceptional versatility, including a Clean channel with Warm (Plexi) and Bright (Class A) modes, a Crunch channel with Crunch and Super Crunch modes, plus two best-in-class high-gain Overdrive channels engineered for crushing rhythm tones and saturated lead sounds.

Blackstar's patented Infinite Shape Feature (ISF) allows seamless control between classic British and modern American voicings, while the patented Dynamic Power Reduction (DPR) system reduces output power without sacrificing valve dynamics or feel. Professional features include MIDI switching, a series effects loop with level switch, Speaker Emulated Output, and dedicated Master Resonance, Presence and Master Volume controls. The rugged 1.6 mm seam-welded steel chassis and birch plywood cabinet ensure long-term reliability under demanding touring conditions.
