Orange OB1-500 Bass Head - 500W RACK MOUNTED CLASS A / B BASS HEAD

(This text is machine translated) For years, bassists have been combining guitar and bass amps with dramatic effects, adding harmonics and overdrive layers from a guitar amp to their basic bass sound, in pursuit of the ultimate live sound. This "Bi-Amp" trend made Orange engineers reflect. Why lug around two amps when you could do it all with just one? The result is the OB 1 series of rack mountable Class A / B a bass heads. The key to the OB1's unique sound is the footswitchable Blend circuit which adds a veil of controllable gain and increased harmonic content to the upper registers of the input signal. The lower frequencies and the clean signal are left alone, remaining warm and clear just as they would be in a bi-amped setup. Depending on how the Gain and Blend controls are set, you get endless possibilities.
