I have messed a lot with the EQ, both circuit-wise and with the controls.
The mid control has very little affect between 9:30 and 1 o'clock, but is very noticeable at extreme cut or moderate to extreme boost. The ear hears the onset of mid BOOST very noticeably, much more than cut, so you have to really cut the mid for it to start being really significant with a fairly 'flat' setting of the passive baxandall bass/treble. But it works well so you can more easily dial in a tasteful boost, if that's one's taste.
Anyhow, I set the mids basically to noon (12:00), or in that area until switching between the 3 frequencies makes no audible difference to my ears. Ultra high is off (equivalent to "0" setting on models with -/0/+)
I boost the bass to about 2:30-3:00, and the treble to about 3:00.
The way I tweaked the EQ caps, that is not as significant a high frequency boost as it would be with the amp stock. It affect the high mids WAY less than the stock EQ.
This boost and particular high boost ends up basically resulting in a midrange cut centered around 500/600hz, which is my preference time and time again, for guitar. It's more around 300 (with a lot more high mid boost) with the stock EQ caps etc.
I run it dead clean and fairly quiet, but my settings don't change much when I've played it loud (before breakup). Great for overdrive pedals, which are admittedly circuits that are hardly recognizable from the circuits they were originally based on...everything goes through various rack-based delay/reverb.
Sweet, fat clean, HUGE sounding lead sound, and everywhere in between sounds awesome too. Highly recommend trying to get a board from hangman that uses a 2.2n/220p pair for the EQ caps on the treble side to anyone who runs their Ampeg clean and feels it's hard to find the sweet spot with the highs.

For more rocking/crunchy tones, I keep the Mids on 300Hz, crank the Mids to around 2/3 o'clock, bass Off.
Thoughts/suggestions?
Enjoy the amazing versatility of the amp! There's hardly a wrong setting!
