Dual Patent Design
Exclusive patented features give Series One unparalleled tone and flexibility.
Two key elements to the Series One design are the patented ISF (Infinite Shape Feature) tone control circuit and the DPR (Dynamic Power Reduction) system. These unique innovations give you a new level of control over your sound.
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.
Better By Design
Traditional construction methods combined with cutting-edge, state-of-the-art 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.
Constructed from premium grade materials and using traditional methods, Series One amplifiers are designed to last a lifetime.Series One Design
