Probably the bypass foot switch, which used to be below the part they incorporated into the rack. Says "in" and "out" if you look close.

I have been wondering the same thing (and apparently there is a thread around here somewhere that covers this, which I can not find) but as an owner of a vintage Mu-Tron III I can tell you the pedal is not a true bypass pedal and your the level of your incoming signal is completely controlled by that gain know even if the effect is bypassed so I think it must be for some other purpose.

It was not to raise the signal in the OBEL since Jerry had each pedal in its own separate loop (at least by the 80's). It could have been used as a "dirt" boost though with envelope effect off (via the toggle switch). There are definitely times that he sounds a bit "dirtier" than his normal clean sound yet not a distortion pedal dirt. Just speculation though.

Here's another link to a thread stating that it was the footswitch moved to allow for the rack mounting. I do concur with mijknahs on the dirt boost thing. I have read that theory around here also but can't find the thread. Greg...
