I have seen a Messenger 2V up for grabs somewhat recently, but have no info on them. And finding info on them is like trying to find an honest politician.
I know it has low / med / high switch, on / off obviously and if I recall receive pre-amp on / off.
I seem to remember these from decades past, and if I recall they maxxed out at around 200w, but the bigger question is, are they a splatter box throwing all sorts of harmonics everywhere and gaining unwanted attention, or do they do their job actually well?
