The 1972 Graphic Mk II is the 'Pics Only' Orange: a 120-watt single-channel head whose front panel used pictograms instead of words. Baxandall bass and treble come before the gain control, a six-position FAC switch voices the midrange, and a capacitor-coupled cathodyne drives four EL34s hard. That rework gave Orange its thick, saturated midrange crunch; this drawing adds a resonant HF boost and an Echo send and return.
