Orange OB1-500 Bass Head – Used
OB1-500 shares the same layout and 2U rack dimensions as the less powerful OB1-300, coupled to a full fat 500 Watt output section to move some serious air. The OB1 splits the input instrument signal into two separate paths. One side amplifies the clean signal, with all the clarity you would expect from Orange. The other adds stages of gain to the upper harmonics only, controllable via the amp’s Gain knob. These two elements are combined using the amplifier’s Blend control which adjusts the mix between clean and dirty. The Blend control can then be remotely engaged or defeated using the optional footswitch.
This head is in excellent condition.
