About Orange Amplifiers OB1-500 500W Analog Bass Amp

OB1-500 500W Analog Bass Amp Head. For years bassists have been combining guitar and bass amps to remarkable effect, adding harmonics and layers of overdrive from guitar amps to their core bass tone in pursuit of the ultimate live sound. This "bi-amp" trend got the Orange engineers thinking, "Why drag two amps to the show when you could take just one?" The result is the Orange OB1-500 500W rack-mountable bass head, which takes care of this and much more. There is also a 300W version, for those who don't need quite as much punch.

These two elements are combined using the amplifier' 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' 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 offensive settings!
