Orange OB1-300 Rack Mountable Bass Amplifier Head, 300 Watts
Out of stock
Unavailable for purchase
The Orange OB1-300 Bass Amplifier Head is a very versatile, 300-watt Class A/B bass head amp, which blends two different tones to create your ultimate gigging amplifier!
The key to the OB1’s unique sound is our footswitchable Blend circuit which adds a veneer of controllable gain and increased harmonic content to the upper registers of the input signal. The lower frequencies and clean signal are left alone, staying warm and clear just as they would be in a ‘bi-amped’ setup. Depending on where the Gain and Blend controls are set, the possibilities are limitless. Punch in the Blend control to achieve anything from a transparent clean boost, to all-out filthy grind, and everywhere in between.
OB1-300 is the 300 Watt version, sharing the same features and 2U rack dimensions as the more powerful OB1-500.
KEY FEATURES
‘BI-AMP’ INSPIRED DESIGN
The OB1 splits the input instrument signal into two separate paths. One side amplifies the clean signal, with all the clarity you would expect from Orange. The other adds up to two stages of distortion to the upper harmonics only, controllable via the amp’s Gain knob. These two elements are combined using the amplifier’s Blend control which adjusts the mix between clean and dirty. The Blend control can then be remotely engaged or defeated using the optional footswitch.
The Gain and Blend’s range allows for almost anything, from a subtle level boost to cut through the mix, added girth and presence at moderate settings to fatten up chorus passages, to fully saturated savagery at the extremes. However you dial it, the OB1 always maintains the critical low end definition, right the way up to the most offensive settings!
ACTIVE EQ
The OB1’s highly responsive active three band EQ has been meticulously voiced for maximum effect with minimal fuss. The EQ section is located after the Gain and Blend dials take effect, allowing full control over their massive sonic range. The Bass and Middle controls feature +/-15dB of boost or cut, whilst there is a range of +/- 20dB on the Treble control.
ALL ANALOGUE SIGNAL PATH
The OB1 Series puts proper class A/B power back on the map. All circuitry is completely analogue, ensuring these amps sound expressive and musical even at ridiculous gain levels.
RACK MOUNTABLE
The OB1 Series are our first rack mountable amps, suitable for 19? cases (2U). Enclosed in a rugged power coated steel chassis the fascia is finished in our classic ‘pics only’ styling.
