I was binge watching all things Page/Zeppelin as usual and upon re-watching Page and JPJ play Ramble On with Dave Grohl and Taylor Hawkins, during the long sustained note solo, I noticed the camera, while doing a close-up on Page, was also doing a good close-up of one of his Orange AD30's.

The settings are in very clear view during most of the solo. However, this is the only frame i found where Jimmy wasn't standing in front of the Gain knob. So I decided, while not as clear as other shots, to post this one as it's the only one that shows his gain (which to me is the least important setting to worry about since it varies on many different things) and the other settings are still clear enough to see.
The settings have marks on the chassis as follows
Master: 5.5 and 6.5
Treble: 4 and 6
Middle: 6.5 or 7 (sloppyish mark)
Bass: 4 and 5
Gain: 6
That may seem pretty flat but keep in mind pot tapers on most amps, especially old british amps, have an audio taper on the bass, and linear tapers on the mids and treble. Meaning his Percentages of signal look more like
Treble: 60%
Mids: 65-70%
and because of the audio taper,
Bass: 10%
