The AD50 is Orange's no-holds-barred tone machine. All valve, and point to point wired with gain, bass, treble and presence and master controls. There's also a footswitchable sustain boost, which bypasses the EQ to give more sustain. A separate rear panel switch allows 50 watts RMS 'Class AB' or 30 watt 'Class A' output selection.
