Orange launches new OB1-500 and OB1-300 bass heads at NAMM 2015

0

British amp manufacturer Orange has announced a new concept in bass amp design at NAMM 2015. The new Orange OB1 takes the basic bass amp platform and adds harmonics and layers of controllable gain, increased harmonic content to the upper registers and overdrive from a guitar amp circuit with a footswitchable Blend circuit. 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, anything from a transparent clean boost to all-out grind is possible.

Both the OB1-500 and OB1-300 share the same layout and 2U rack dimensions.

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 extreme settings.

Active EQ
The OB1’s highly responsive active three band EQ has been meticulously voiced for maximum effect with minimal fuss. With +/-10dB of boost or cut, the EQ section is located after the Gain and Blend dials take effect, allowing full control over their massive sonic range.

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.

Balanced & Line Outputs
Balanced DI with ground lift and line level outputs for live and studio use.

Although he has been playing for longer than he cares to remember and is now officially an 'oldie', he is still mad for all things guitar related and when not busy in his studio he's learning new songs, practising bluegrass guitar, painting his house and taking his dogs out. If banished to a desert island and forced to take only one guitar he'd take a Les Paul. Actually, make that several Les Pauls, a Strat, a Tele, an ES-335, a vintage Martin and some boutique amps. Battery powered obviously.
