The New #1
Series One are the ultimate professional high gain valve guitar amps. At home, in the studio or on the road, our award-winning Series One valve amps will always deliver. Whether it’s build quality or tonal excellence, no compromises have been made – if you are looking for the ultimate, professional high gain valve amplifier, why compromise? We didn’t.
Dual Patent Design
The cornerstone of the Series One design is the two patented circuits: the ISF (Infinite Shape Feature) tone control circuit and the DPR (Dynamic Power Reduction) power reduction system.
These technologies are exclusive to Blackstar Amplification and are the result of many months of in-depth technical research. The inclusion of ISF and DPR allows you to take the Series One’s highly developed sound palette and tune it exactly to your own sound signature and create ‘the sound in your head’.
ISF and DPR are perfect examples of Blackstar innovations that, through technical research and development, can significantly improve your performance and creativity as a guitarist.
Better by Design
Every aspect of a Series One guitar amp is the result of uncompromising care and attention to detail, both for tone and reliability. Our experienced R&D team in the UK refined every aspect of these amps to maximise the tone through hundreds of hours of listening tests.
The Series One range is built to withstand the adversities and demands of life on the road. That’s why all Series One amplifiers have plated-through double-sided PCBs, seam welded 1.6mm steel chassis and 18mm finger-jointed birch ply cabinets, with ‘over-specified’ output and mains transformers constructed using laminations made of the highest grade, grain oriented steel.

DPR (Dynamic Power Reduction)
DPR allows continuously variable power reduction so you can use your valve amp in any playing situation and achieve pure valve output distortion and compression at any volume. DPR is a 'dynamic' circuit, delivering the exact compression (a.k.a. sag) of a small overdriven valve amp, at any volume level. The power is reduced, the feel, tone and reliability of the amplifier is maintained.
Every control has been honed for maximum sonic benefit through hundreds of hours of listening.

ISF (Infinite Shape Feature)
The ISF control allows you to infinitely adjust the response of the tone control network between any of the traditional voicings in a way that has never before been possible. The whole tone stack response (i.e. Bass, Middle and Treble) is moved yet the tone controls remain fully interactive, just like in a regular tone stack.
The ISF control is continuously variable between all the traditional responses allowing you to effectively design your own sound.

Built to Last
Constructed from premium grade materials and using traditional methods, Series One amplifiers are designed to last a lifetime.
Every aspect of a Series One guitar amplifier is designed to deliver not only the ultimate tonal performance, but also reliability capable of withstanding the rigours of life on the road.
Our Technical Director Bruce Keir has been designing valve amplifiers since he was a child and it is obsession with no-compromise design that leads our R&D team to excel in all areas of the construction of Series One amps.
