For years bassists have been bringing two amps to gigs; one bass amp, one guitar amp, and using the best features of both to create incredible effects, whilst leaving the low end frequencies untouched. Known as bi-amping, this technique helps musicality by offers additional harmonics and overdrive. The solution to the issue of lugging around two amps is the far more compact, 500-watt, class A/B Orange OB1-500 rack mountable bass head.
Giving you the same control over your tone as having two amplifiers, the Orange OB1500 Bass Head splits your signal into two paths: lower frequencies and upper frequencies.
The lower frequencies are left clear and warm; unaltered by effects and retaining definition. The upper frequencies is where all the action takes place, with two stages of distortion, controlled with Gain and Blend controls, giving the additional harmonic content. The Blend control adjusts just how wet or dry your mix is and can be engaged via a footswitch or the on-board controls.
This set up gives you easy control but a surprisingly broad range of accessible tones, for everything from subtle level boosts or extra girth to a fattening of chorus parts or all-out filth.
Full Scope EQ
In the chain of events, the Orange OB1-500 Bass Head’s three-band EQ engages after the Gain and Blend have done their thing, to give absolute control over your sound’s dynamics. Boost or cut can alter bass and middle within +/-15dB, and +/- 20dB to trebles.
Even when being pushed to the limits, the Orange OB1-500 Bass Head still offers an exceptional level of expressiveness and musicality, thanks to its all-analogue circuitry. A balanced DI with ground lift and line level outputs give useful connectivity options. Of course Orange’s standard rugged and good-looking design is in place, with the powder coated steel chassis and Orange’s usual ‘pics only’ control icons, plus the whole unit will fit in a 19-inch (2U) case.
