Orange Dual Terror High Gain Option

These amps are cathode biased, there is no bias adjustment to be made. The amount of clean headroom you’ll get from the power section is somewhat dictated by the grade of power tube used. A cooler grade of EL84’s will give you more clean headroom, whereas a warmer grade will give you earlier breakup. If you order online, leave us a note in the comments section letting us know your headroom preference (max headroom, middle of the road or early breakup).
