Need clarification modding Arion SCH-Z - instructions and schematics inside

[banjerpickin]

Hey guys, I am trying to mod an Arion SCH-Z for my friend to have the popular "tremelo/vibe" mod that basically cuts the dry signal out of the mix when you move the mono/stereo switch.  I found verified instructions here http://www.....org/viewtopic.php?f=1&t=7249

- Isolate the switch by removing C5 and R39.
- Disconnect C28 and R38 at the switch side
- disconnect R40 at the switch side.
- Connect the disconnected side of R40 to the junction of C28 and R38 where they used to be connected to the switch side.
- disconnect R34 and R28 from U1b, pin 7.
- connect one of the outer isolated lugs of the switch to the junction of R28 and R34
- connect the center lug of the switch to U1b, pin 7.

However, I can't for the life of me figure out how to disconnect R34 and R28 from pin 7 of IC1 because it doesn't look like they are connected at all on the board following traces.  Here is the schematic, which shows them directly connected: https://1.bp.blogspot.com/-TOI7Uj5yzRw/WLlklL3-bMI/AAAAAAAAAS4/ZDTgQZ3VylYPzbWpoKZdIi8StBYhQuLyACLcB/s1600/Arion_SCH_Z_sch.gif

Here is the board, where the trace coming from U1, Pin 7, doesn't end up hitting either resistor:

Any help our guidance would be appreciated!

Is that a jumper on the topside of the board to the left of those resistors?
