BE-100 S switch?

[SkyhighRocks]

Got my BE this week and love it so far. I guess I was sent an old manual because it doesn't show the switch on the far right which I'm guessing is a gain structure switch? Can anyone tell me what the 3 positions do?

Center= lowest gain
Left= medium gain
Right= highest gain

That was my guess...thanks!
