All valve, 100 watt, channel switching head with valve FX and valve driven reverb. This amplifier has the same pre-amp channels, pre-amp and FX loops as the Rockerverb 50 but has the original Orange 100 watt output stage. Two additions to this output stage are the output valve fusing system and a special bias switch which enables you to use quartets of output valves of different types (6CA& / EL34 / 6L6 / 5881 / KT88), A quartet of 6CA7 / EL34 come as standard in this head, along with our new and unique 'Reverse Snake 8' output transformer design. We at Orange think you'll agree that the Rockerverb 100 is the best sounding ever in its class.
