Introducing the Orange OB1-500 500-Watt Single Channel Solid State Bass Head, an innovative bass amplifier that combines the best of guitar and bass amplification in a single, convenient package. This powerhouse unit makes it easier for bassists to achieve the layered, harmonically rich sound they desire without the hassle of hauling multiple amps to a gig.

The secret to the OB1-500's unique sound lies in its footswitchable Blend circuit. This circuit adds a controllable gain and increases harmonic content in the upper registers of the input signal, while leaving the lower frequencies and clean signal untouched. This results in a warm, clear sound that replicates the bi-amped set up bassists love.

The possibilities with the OB1-500 are limitless, thanks to the range allowed by the Gain and Blend controls. From a transparent clean boost to a filthy grind, everything in between is achievable. Plus, no matter what settings you choose, the OB1-500 maintains critical low-end definition.

The OB1-500 also features a highly responsive active three-band EQ, meticulously voiced for maximum effect with minimal fuss. The EQ section is located after the Gain and Blend dials, allowing full control over their massive sonic range. The Bass and Middle controls offer +/-15dB of boost or cut, while the Treble control provides a range of +/- 20dB.

• Single channel bass head with bi-amping capabilities
