{"product_id":"blackstar-series-one-100-mk-ii-head-401814","title":"SERIES ONE 100 MK II HEAD","description":"\u003ch3\u003eHistorical Context and Positioning Within the Range\u003c\/h3\u003e\u003cp\u003eOriginally introduced in 2007, the Series One established itself as Blackstar's \"high gain\" flagship, with a clear philosophy: massive gain reserves that remain controlled, usable, and musically precise. The \u003cstrong\u003eMK II\u003c\/strong\u003e version represents a refined evolution of this platform, announced as deeply optimized with numerous circuit improvements. Within the lineup, the \u003cstrong\u003eSeries One 100 MK II Head\u003c\/strong\u003e serves as the high-performance professional head: targeting demanding stage and studio use, with modern ergonomics (MIDI, effects loop, emulated output) while retaining the feel of a powerful tube amp.\u003c\/p\u003e\u003ch3\u003eWho This Amp Is For\u003c\/h3\u003e\u003cp\u003eThis head is made for guitarists who prioritize \u003cstrong\u003eprecision\u003c\/strong\u003e and \u003cstrong\u003etight low end\u003c\/strong\u003e in their playing: modern metal, metalcore, death, thrash, djent, hard rock, but also any style requiring dense crunch and clear saturation. With its 100 watts of all-tube power, it is aimed at musicians playing in \u003cstrong\u003erehearsal with a drummer\u003c\/strong\u003e, on \u003cstrong\u003estage\u003c\/strong\u003e, and in \u003cstrong\u003estudio\u003c\/strong\u003e, or those who want huge clean headroom and plenty of margin for pedals. In home studios, the DPR helps maintain the amp's touch and response while lowering power, allowing work at levels more compatible with close miking.\u003c\/p\u003e\u003ch3\u003eFeatures and Innovations\u003c\/h3\u003e\u003cp\u003eThe Series One 100 MK II focuses on a \u003cstrong\u003e4-channel\u003c\/strong\u003e performance-oriented architecture: a Clean channel with two modes (Warm Plexi-style and Bright Class A-style) to switch from a round, thick clean to a brighter, snappier tone, then a Crunch channel with Crunch and Super Crunch modes to cover everything from sharp rock to heavy saturated rhythm. The overdrive channels are designed to deliver massive \"high gain\" with particular attention to \u003cstrong\u003esignal clarity\u003c\/strong\u003e and reducing the hiss often associated with very high gain levels.\u003c\/p\u003e\u003cp\u003eSound shaping is enhanced by the \u003cstrong\u003eISF\u003c\/strong\u003e (Infinite Shape Feature), which allows shifting the EQ and voicing center of gravity between more \"American\" tendencies (tight lows, incisive highs) and more \"British\" tendencies (present mids, rougher grain). The \u003cstrong\u003eDPR\u003c\/strong\u003e (Dynamic Power Reduction) power management adapts the response and feel under the fingers according to context, without losing the identity of a true tube power section. For global control, there are \u003cstrong\u003eMaster Resonance\u003c\/strong\u003e, \u003cstrong\u003ePresence\u003c\/strong\u003e, and \u003cstrong\u003eVolume\u003c\/strong\u003e knobs to adjust low-end foundation, high-end openness, and overall level.\u003c\/p\u003e\u003cp\u003eFor integration into a modern rig, the head offers \u003cstrong\u003eMIDI implementation\u003c\/strong\u003e, a \u003cstrong\u003eserial effects loop\u003c\/strong\u003e with level selector (handy for balancing pedals and multi-effects), and a \u003cstrong\u003espeaker-emulated output\u003c\/strong\u003e, ideal for quick recording, feeding a PA, or keeping a simple and effective backup option. Finally, the entire unit is built to last: welded steel chassis, birch cabinet, more robust and contemporary aesthetics, and a clearly tour-oriented approach.\u003c\/p\u003e\u003ch3\u003eThe Sound\u003c\/h3\u003e\u003cp\u003eAll-tube, the Series One 100 MK II stands out with a \u003cstrong\u003edense\u003c\/strong\u003e grain and \u003cstrong\u003efast\u003c\/strong\u003e response, with dynamics that follow the pick attack and natural compression from the power section when pushed. Cleans range from warm vintage tones to sharper cleans useful for arpeggios, chorus sounds, and funk-rock lines. The Crunch channel serves as a perfect bridge between organic overdrive and muscular rhythm, while the overdrive channels deliver modern saturation: \u003cstrong\u003etight lows\u003c\/strong\u003e, controlled mids, present but tameable highs via Presence, and gain levels that remain clear on complex chords. The ISF allows fine-tuning the guitar's place in the mix, whether you want a wide, \"scooped\" guitar wall or a more mid-forward projection to cut through live.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr)
