SERIES ONE 412 PRO B SPEAKER CABINET
The Series One was first introduced at the Frankfurt show in 2007, during the brand launch. It has always been our flagship range of 'high gain' amplifiers and is the most awarded line we have ever released. Featuring two patents (ISF and DPR), the Series One has been a dominant force on the rock and metal scene for nearly twenty years, used by some of the biggest artists in the world. Driven by a desire for sonic perfection, we have used everything we have learned about amplifier design over the past 19 years to further enhance this iconic platform.
Here is the Series One MK II, an improved and optimized range designed to be the ultimate modern amplifier and speaker cabinet, specifically tailored to the needs of today’s metal guitarists. This evolution of the series marks a significant advance in high-performance 'high gain' amplification, with the Series One 100 MK II 4-channel head at the forefront – a high-gain amplifier designed to deliver incredibly tight rhythm tones and big saturated leads, without the unwanted 'whistle' often present in other models. This monster amplifier benefits from over 30 circuit modifications and tweaks compared to its predecessor, allowing us to confidently state that it is the pinnacle of 'high gain' amplification for today’s metal guitarists. The Series One 412 PRO A/B MK II cabinets, the perfect companions to this 'sonic weapon,' are equipped with Celestion Vintage 30 speakers exclusive to Blackstar and feature a special cabinet construction offering a more balanced midrange response. In addition to these sonic improvements, we have also revamped the aesthetics of the Series One MK II to give it a bolder, more robust, and contemporary look that stands out on stages of all sizes. This is not just about looks and sound, as this range is built from the finest materials, including hand-jointed 18mm birch plywood cabinets, 1.6mm welded steel chassis for tank-like durability, and sturdy metal grilles. These amps are designed to withstand a lifetime of intense and abusive touring use.
The Series One MK II represents the pinnacle of our commitment to innovation by offering the ultimate tools for self-expression. Our heritage is deeply rooted in pushing the boundaries of sound design and a future guided by dedication to perfection. This amplifier sets a new standard for metal guitarists seeking uncompromising performance, flawless quality, and reliability, with an amp that will deliver night after night, stage after stage, city after city.
