Help with rewiring a vox V847 wah. EDIT: Now with pictures

[Guybrush]

Hi all

I'm looking to add the following mods to my Vox V847:

True bypass switching
LED
DC jack

The only wiring diagram I can find that shows all three of these mods for my specific model of wah is the one in this very grainy image



I'm redrawing the image to make it easier to read, but need some help with the 3pdt please.

From the image, it's difficult to tell which way round the original creator has drawn the switch. The 'regular' way is to draw the 3pdt with the lugs running horizontally, but the image looks as if they might be running vertically...






I'm hoping that someone cleverer than me will be able to work out which way round the switch is shown in the wiring diagram from the way the other components are connected to it.

Any help would be greatly appreciated.

Horizontal lugs, with #1 at the top left corner.  The tip-off is the LED, the cathode side must be grounded when the effect is active, so the swing contacts work north-south and not east-west.

Thank you. That makes sense. Appreciate it!
