Super noob back again. Are the pots usually numbered facing the front or back?

Thank you as always pedal wizards

Yes, front or back.

It took me a while to remember the numbers of the lugs for some reason. Maybe i'm just kinda slow. But i finally got it when i thought of the side with the shaft as the front, since it's what faces you with a knob on it when you use it. The other part to remember is the lugs need to be below the shaft (when you're looking at it) for the numbering to be 1,2,3, left to right. If they're facing up, it's backwards. Fun huh? You'll get used to it after a while.

I can't speak for you, but I am slow. I feel like I've seen layouts where the pots are numbered in reverse as well, so never sure
Thanks!

Kinda hoping I wired pots wrong, would explain why It doesn't make sound ;D
Thanks!

if you are talking about the proco RAT, the tone pot should be reversed, just like the original.

You just saved me a lot of money!
Hang on, i think when it comes to PCB mount pots it doesn't matter if they're upside down no?
I've got a few boards with upside down pots and they're also bottom mounted so it's making my head hurt. But what's connected to pin 1 on the schematic is connected to pin 1 on the pcb irregardless...so it's fine if they're upside down? Or maybe it's not? God i don't know anymore
^ of course it's fine! And of course, lug 1 is always lug 1. It's just a matter of what perspective you have vs. the pot. I only meant that if you hold it with the lugs pointing upward, the lugs are numbered from left to right, 3,2,1. If you hold it with lugs pointing downward, it's 1,2,3. That is, if you're holding it with the shaft pointed at your face. One way to slow the confusion down while building is to hit the backs of the lugs or the pot casing with some kind of marker on lug 1. Then you'll always know which is which, no matter what your perspective. It can get a little hairy while cramming everything in, real easy to make mistakes.

Putting a pot in backwards won't stop it working. You'll still get sound (all other things being equal). But for log/antilog pots you might find that it doesn't feel natural when you turn it: all the audible changes may appear bunched at one end or the other. For linear (and log) pots, you might find that "loud" or "deep" is at the wrong end. But it still makes sound!
do potlegs have numbers now? so I can't use ccw and cw and w any more?
> I can't use ccw and cw and w any more?
No. Some people live other side of equator, and their drains spin the other way around.
I always liked an arrow pointing to the pin nearer "UP", which could be interpreted to local expectations.
The easy way to remember the pot number is to visualize a volume control dialed to "10" which is the highest number setting. At 10 the volume control connects the wiper (2) to pin 3, which is the highest number terminal.
When looking from the front, 10 is when you wind the knob clockwise ie. max-out the volume control
To workout the physical pin: Look at the pot from the front. Imagine what is going on inside. When you max-out the pot to "10" the wiper moves clockwise around the track and it will eventually hit the end-stop. That will be pin 3.
Look at this pic, which is viewed from the front:

See figure 6 for the schematic. Plenty of other info there as well.
