Not sure "headroom" is what you're trying to achieve with the Mutron boost (envelope off). Seems more like the boost effect is to achieve some type of overdrive effect from pushing either the Twin, the McIntosh, or the JBLs (or some combination of each). Or maybe to "heat up" the signal before it hits the distortion pedal? Basically more volume to push things into a "crunchier" zone.
I agree that it's a clean but louder tone. It itself doesn't clip (it's clean) and it preserves the original guitar "tone" but the effect is that it pushes something else into some type of clipping/overdrive. Again, not really that different from other boost pedals for practical purposes.
