Why is the Mesa so damn loud? Not that it's a "bad" thing, but... maybe impractical. I got the Marshall a while ago and have it set for rehearsal and live at about 4.5 on the volume dial for both clean and dirty. Clean is pretty clean, with gain at about 2.5, and Dirty is moderately heavy, about 6 on the gain dial. With roughly the same sounds dialed in on the Mesa the volume sits at about 2 on the dial, if that. Any more and it just blows us all away. I'd like to hit the sweet spot, but I'd need armor. Why is the Mesa so much louder at 25 watts than the Marshall at 40 watts? The DSL is a combo with a 75 watt creamback. The ROV head goes through a Marshall JTM 2x12 with G12 Heritage. I use the 2x12 with the DSL, too, but there's not much volume difference vs. the combo alone. Resistance ohms are matching.
