If your clean channel is loud, then that rules out output tubes and effects loop, unless you are turning off the loop when you got the clean channel.
I would get some replacement preamp tubes, and starting with V2 and start replacing them one at a time to see if you find a bad one. Reason i say to skip V1 is because that is input for all three channels and since you say your clean is working fine more then likley that preamp tube is fine.
Exmaple, Replace V2 if the problem still persists put back in the original and then replace V3, if the problem still persists replace the original V3 and try replacing V4 and then if still bad try V5. If the problem still there then try replacing them all just in case you have more then one that is bad.
Reason you do it this way instead of replacing all right away is, if you replace one at a time you can find the bad tube so you can throw it out. Plus also helps you down the road if all of a sudden you have the same problem you can tell if it is the same tube burning out, if it is might be a problem with that stage and would help a tech locate the problem quicker.
If non of this works, and you have removed the loop completly, checked your speaker cable and make sure all connections are right. If this does not fix the problem then I would bring it to get serviced, if it is brand new it should be under warrenty, if you bought it used, well that is the price you pay sometimes for saving money instead of buying a new one.
PS- also check all your input cables, I use to have an issue where I could hear the volume swell, not major, but I could only hear this on the channels with distortion, and it ended up one of my patch cables was going bad.

So then, try dis-engaging the loop (hard bypass switch), and use the channel masters, to see if the problem persists!
Yes it keeps persisting!! GRR!! I feel like im not getting that MESA sound and it sounds like when i turn it up its like already at it's limits at like 5 or 6. It starts to get really pushy and what happens is wierd. I'll play a chord (with it on like 6) and it'll be loud for 1 second then go soft right away after.
This pisses me off so much cuz i spent like 2100 on this thing and it isnt living up to its potential!!!!!
