Hmmm, I'm not sure about all these "add x amp settings section" suggestions. There was one recently for the studio pre.
When it comes to mark amps, they're all pretty close, so if you're looking for a starting point, someone's settings for any of the amp series will do fine for you. This worked for me with the studio pre, which is pretty far from mark IV especially considering the different poweramp, so it should work for any mark series.
I doubt one person's settings will be perfect for many people given different guitars, speakers, tastes and playing style, so everyone's going to be doing some tweaking and any mark settings will make a good starting point.
What I think is more useful is general advice about how the controls on mark amps work, which this board is pleasantly full of, and rather than just a list of numbers, people saying what they do (eg. the 'I dime my mids' thread) for what style and why.
