Vh drive pedal changes to original design

[paulig174]

Im in the process of building the vh140c pedal from aion(vh drive pedal). But im bullilding it onto a custom case.
My first question is
.. can i bring wires from the pots to the board.. so i can move the pots to the front the case rather soldering directly to the board (as it is in instructions) or will it cause cross talk or volume /gain drop? what gauge wire should i used if i can to this?
Next question if i want the footswitch to be on a sperate pedal(via a 1/4" jack and cable to the floor rather than soldering the switch directly to the board would this work or would the long calbe also cause problems?

1) you can off board wire the pots but yes, it may cause issues
2) using a relay bypass would be the easiest way to do this. Then you just send the 5v trigger out on the jack. Take care to use isolated jacks so not to ground the 5v signal.
Since this has the overly complicated Aion daughter board, it will take a bit more effort than typical.

Are you top mounting the pots? They look really close together if that's what the 5 dilled holes are for. Unless you're planning on 9mm pots, even then , pretty cramped.

Oh yeah the pots are 9mm are they big enough? What gauge of wire could i use to off board the pots?i might not do bypass switch mod so.. ill just put the switch on the back of the box.

I’ve off-board wired the majority of pedals that I’ve built.
A.) because it was the norm on older stuff
and
B.) because I frequently don’t like other people’s default layouts
I’ve never had any problems with it.

And as far as I know, the main reason for PCB-mounted pots is so you don’t have to use standoffs or some other way of securing your PCB inside your enclosure (something you might need to consider here, btw), not for any electrical/signal quality advantage it’s supposed to confer.

9mm pots should work fine. They can be tricky to solder though, due to their compactness. I’ve only ever seen them with the ‘straight pin/PCB’ style lugs (as opposed to actual round solder lugs). So if I’m using them, I carefully bend the lugs into loops using some small round-nosed pliers. Center lug bent one direction, two outside lugs the opposite way, to reduce crowding. Then heat shrink over each when I’m done.

24 or 22 AWG should be fine for any pedal wiring.
