its the same thing.
Some bozo in marketing probably thought that the "high overload" and "moderate overload" sounded cool. notice, none of them say "low overload".
frankly, I have no idea what they're talking about. The sensitivity switch is a slight gain boost. it basically adds a cathode bypass cap on the first gain stage of the preamp, which boosts the gain of that stage. The original intention was to be able to have a switch that allowed you to plug in your les paul for one song, then switch to your strat, flip one switch and not have to move any of your other controls. I'm not so sure anyone ever actually used it for that, and most people I know use the 0db setting.

I've just seen in the 1971 Ampeg catalogue (the one that's in the docs section of the site) something that I don't understand very well.
The last page of the catalogue is about V-4 specifications. It's written that the sensitivity switches have 3 positions:
pos. 1: Normal sensitivity with high overload
pos. 2: Medium sensitivity with moderate overload
pos. 3: High sensitivity with easy front end overload
On my Master Volume VT-22 next to these rocker switches it's written -9db/-6db/0db.
So, is it the same thing or is there something different in mine/MV models?
Thanks!
