Attempted comprehension of hi and lo input jacks

[saturated]

I was looking at a peavey schematic VSS Audition Chorus specifically the input jacks region

I wanted to draw it out and figure out the paths of each

Nothing plugged in

You cannot view this attachment.

Plugged in to low

You cannot view this attachment.

Which looks reasonable because a circuit is completed

Now if I plug into high I'm not sure what's going on

You cannot view this attachment.

....now...of course the rest of the amp is downstream and there are a couple of grounds chassis and earth in that vicinity

Just wondering what the signal path is

You've got your drawing of the plug wrong.  The tip goes to the part of the jack that looks like a check mark.  The arrow is a switch contact of the jack, it does not contact any part of the plug.
