OB1 SERIES USER MANUAL
INTRODUCTION
In 1968, Orange founder and CEO Cliff Cooper borrowed £50 to start a musical instrument shop and recording studio in London’s West End. Against the backdrop of one of the city’s most vibrant districts, the shop was decorated with psychedelic script and painted a bright shade of orange which gave the company its name.
Shortly after, Orange began designing and manufacturing products which quickly established a reputation for their innovation, superior quality and distinctive sound. We have been a pioneering force in the guitar amplification industry ever since, and today, with a team of the world’s finest amplifier engineers we continue to push back the boundaries of conventional amplifier design. From our very humble beginnings on New Compton Street, Orange Amplification has grown into an iconic global brand, earning legions of loyal supporters along the way who continue to make the ‘Voice of the World’ heard.
We are confident that you will be delighted with your new purchase and that it will provide you with many years of enjoyment. Congratulations, you are now a member of the Legendary British Guitar Amplifier Owners Club!
THE OB1 SERIES
For years bassists have combined guitar and bass amps to remarkable effect, adding harmonics and layers of overdrive from a guitar amp to their core bass tone in pursuit of the ultimate live sound. Taking our inspiration from this ‘bi-amping’ trend, the OB1 Series takes care of this and more besides, with its unique Blend and Gain circuit. The result is a ‘bi-amped’ sound, without the hassle of taking two rigs to the show.
The OB1 splits the input signal two completely separate paths. One side amplifies the clean signal, whilst the other adds up to two stages of controllable gain to the upper register. These two elements can then be combined using the Blend control. The low end remains warm and punchy, whilst the overall tone is enhanced with additional harmonic content from the Gain circuit. Dial in anything from everything from fat cleans to heavy grind, and everywhere in between.
