for what its worth concerning the MoP tone...
1. The cabs were Marshalls
2. They slaved the IIC into a marshall amp... thus there is a mix of the IIC power section and the Marshall power section
3. No EMGs on the recording
They used a mix of Marshall cabs and they also used the old Metal Grill Boogie 4x12's.
And if you slave a IIC into a Marshall you're only using the preamp of the IIC, not the power section. I've tried it with a Mark III and a Mark IV. If you use the slave out of a Mark III into a IV, then the IV controls the volume since you're using it's power section. The III only uses the preamp so it won't affect the volume.
Unless the slave on the mark's work different from the recto's, if you have your IIC+ hook up to a cab and you slave it to another power amp (or power section of another amp), your using both amp's power secton and only the IIC's preamp. This is how I accomplish a W/D/W setup.
Yes, this is correct.
When you SLAVE an amp into another, it means you are using the Slave Out, which is derived straight from the Speaker Outputs, meaning the sound includes both the preamp section and the power section of the amp. This is in other words not the same as using the FX loop send. So when you are slaving an amp into another (assuming this is the way Mesa defines slaving and how it is used in conjunction with their amps), you are using the whole amp (both the preamp section and the power section) as a line level preamp (because the speaker level signal at the speaker outs is trimmed so that it can match the input of line level devices), which means that you get the coloring effect from the power section included in that signal, as opposed to using the preamp signal only. The power section then only acts as another coloring preamp section, though, not as an actual power section, as it's not really driving a speaker.
When you are using the preamp section only, you are using the Effects Loop Send with another amps Effects Loop Return. This can in some cases also be defined as slaving, as it technically is the same procedure when looking at the relationship between the two amps, but when talking Mesa, it usually means using the Slave Out into another power amp/effect processors.
Danyeo is right about there not being two power sections in effect (even though the first amp will still control the volume, just like any master/volume control before the power section will), but technically, if they slaved the Mark IIC+ into the power section of a Marshall, there was coloring of both the Marshall's power section and the Mark IIC+. Not equal to using both power sections next to each other, though.
In terms of how this whole procedure affects the tone, it is very hard to come up with an exact analysis, but in any case, there is a major difference between Slaving an amp into a power section/poweramp and simply patching the preamp out/FX loop send into another power section/poweramp.
