Orange Amplification Announces OB1 Bass Amp Series

Orange Amplifiers has announced the OB1 Series of class A/B rack mountable bass amplifiers. The amps are based on recent bi-amping trends, the company says.

“For years bassists have been combining 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,” Orange explains. The OB1 splits the input signal into two separate analog paths: one clean and one with extra gain. The latter adds two stages of gain and increased harmonic content in the higher frequencies. Both the clean and driven signals can then be blended together and controlled with a mix knob. A footswitch jack allows for on-the-fly blending.

The lineup includes the OB1-300 and OB1-500, rated at 300 watts and 500 watts, respectively. Both fit into a 2U rackspace. Other features include a 3-band EQ, a balanced DI, and line level outputs.

    I definitely would love to try one of these out! I have been looking for an all solid state amp head as I already had a pre amp tube in my Orange Terror Bass fail on me unexpectedly.
