This is an experience that everybody complaining about the learning curve on a modeler/profiler should do. Studio 22, Mark II, Mark IV and LS....Mark IV was like the Rubik Cube...
I have a Roadster. Man, that thing is beautiful and as much frustrating. Soooo many options on it and everything feeds off of everything else in it. You get it close to what you want then adjust one knob and start over.
To be fair, it is isn't just Mesa/Boogie. I have a hand built Marsh amp. It has the Overlord mod on the left side. That basically adds a Dumble circuit into it. All 3 knobs on the front for that channel are push pull knobs that affect tone. There are two additional knobs on the back for Overdrive. I can get that thing sounding really good but need to turn it up a bit and I get to start over. You really have to dial it in at the volume you will be using it at because all of the knobs feed off of one another.
