Not exactly a pedal question, but does relate to pedal components/electronics... I've posted this elsewhere, and emailed both Stew-Mac and CTS. I hope that it's okay to post here, if not delete it. 
Anyways, I'm getting ready to wire up my new project Les Paul with the 50's style Jimmy Page scheme, via the tried and tested Breja Toneworks video on youtube, but he appears to use Alpha pots with the traditional style lugs. I ordered CTS DPDT pots from StewMac, since I have used CTS in the past and prefer them. However, CTS uses a completely different pad identification than the Alphas. Just trying to be sure I'm labeling my pads correctly before I jump in.
If I use the identifiers from the Breja video, A1=4 A2=C2 A3=3 B1=2 B2=C1 B3=1. Looking at the pics, can anyone tell me if this is correct? Or does CTS wire their internals differently than Alpha?
Attached are pics of the CTS with PCB and pads, Alpha with lugs, and the ID scheme from the Breja wiring diagram and video...

I think you've got it right. However, even if A1=3 and A3=4 it wouldn't matter, as long as you apply the middle pin as centre pole and treat both sides A and B the same (e.g. pin 1 are the upper ones, pin 3 the lower).
Good luck

Per Don@Breja, I actually reversed them. Correct ID would be:
My ID = CTS ID
A1 = 1
A2 = C1
A3 = 2

B1 = 3
B2 = C2
B3 = 4

There's a diagram comparing the CTS to Alpha buried on the StewMac site, but they didn't include it with the rest of the wiring diagrams they sent with the pots. Hopefully this will help anyone else who needs to compare the two companies in the future.
