[quote=umasstele;1573908] Does anybody know the settings he used? I heard a rumor awhile back that it was everything on 10 and reverb on 2.

I've heard the same thing, but I'd wager he twiddled the knobs to fit the situation. A twin with volume on 10 will be painfully loud. Sound pressure levels that would get you thrown out the door nowadays were tolerated back then, as well. So, unless you contemplate playing the Fillmore in 1967, I'd be open to experiment. Running the bass on 10 with the volume up high is likely to get some
interesting sounds out of your Utah speakers and even send them to their doom, so use caution, especially if you're using some type of pedal to goose the front end. I had my first silverface twin for 6 years and destroyed 4 speakers with it. (see sentance #3, above)
I used to set mine on 7, 5 and 3.5 (Treble, Mid, Bass) and reverb of around 3: but I
always changed them from there depending on volume levels, room size, etc. But, I'd take all settings that you read, (Including the ones I just mentioned) with a grain of salt: there are too many variables for them to be of anything but a rough guide.
Remember, we're talking about the era when people first began to use multiple Marshall stacks on stage, and most PA systems were not very good, often only amplifying the vocals. (and often lacking any monitors on stage) There were a number of strange rigs used to get the sound to the last row in a hockey arena or outdoor festival. Here's John Cipollina of Quicksilver Messenger Service's rig:

I bet if I plugged into it I wouldn't sound a
thing like him.
I'm betting that Marshall pedal will work quite well to slam the front of that Twin. If you've liked the way it's sounded with other tube amps, you'll
probably like it in this case. My experience is that Twins respond quite well to pedals of all sorts used in boost mode. Nearly every guy I've seen use a Twin seems to use some sort of pedal in front of it
