Tone Bender Mk.3 broken fuzz pot.

Hi again

I recently put together a Total Bender from PCB Guitar Mania which is 3 tone benders in 1. I managed to get it working with mk3 as a PNP. Link to previous post (https://www.madbeanpedals.com/forum/index.php?topic=34523.msg330029#msg330029)

However I have managed to break it and am hoping that someone can assist.

There was too much pressure on the fuzz pot so it only worked at around 10% and 100%. I reflowed solder on the legs of the pot and pushed it out to relieve pressure, however I think i removed the PCB trace rings around the pot so the connection is poor.

An audio signal does come out but it is very faint. An audio probe shows that the fuzz pot is the likely culprit as the audio signal is great until c3.5 on the schematic which is just before the fuzz pot. The signal on fuzz pot and q3 is very quiet.

QUESTION

To repair this, would i essentially solder jumpers from the 3 legs of the fuzz pot to the relevant components? I.e.:
- leg 1 to c3.5
- leg 2 to base of q2
leg 3 to positive end of d1?

Below are pics of the schematic and the PCB. I tried to solder jumpers as discussed but I think i got the legs wrong on the pot. It now does not work at all. Is it 1,2,3 from left to right with the pot facing you?

Also does it matter which leg of c3.5 I solder leg 1 of the fuzz pot to?

Further on the schematic i see d1 and base of q3 are connected. Could I solder leg 3 of the fuzz pot to either of these?
