Preset's not terrible. You're on the right track. I'd lose the drive though. If you can't get enough gain from a Mark IV, you're probably doing something wrong. Boogie amps can be tricky to dial in. The pre-gain tone stack needs low bass settings to stay tight. Somewhere in the 1 to 2 range works ok. Turn on the bass cut switch if your guitars are bass heavy too. I also prefer the Mark IV with the presence knob on about 3.5 and pulled (presence shift on). Gives a smoother, less harsh high end. The graphic EQ makes a huge difference too. It's post gain so you can push the bass back up there an not make it flabby. Use the tone stack to shape the texture of the gain and use the graphic EQ to shape the tonal response. Beyond that it's finding the right cab. The right cab is everything. Advanced parameters are not really needed IMHO. Some folks also find the USA Pre LD2 Ylw model easier to dial in. It's the Mesa TriAxis version of the Mark IIC+ sound, which JP also used on tour for years.
