Yes, but if you switch scenes, the amp volumes track channel changes, which is extermely helpful.Yes, single preset, single scene. My guess is that we'd need a flux capacitor to run all presets or scenes at once.
If you are running a single amp block, you could copy another preset's amp block in and switch back and forth between them to compare levels and adjust. I just set the amp to tickle the red on the outputs when my lead boost is engaged. Seems to work well most of the time....
