To my shame, I have to admit that I sought out the following pic to confirm
the wiring to the Alps pots I received today for the purposes of mending my
'dog's bowl' attenuator:

Thankfully, the picture confirms what I suspected and was trying to
remember (specifically Earth on Pin 1 - both channels), but the labels
read quite clearly signal 'in' and 'out' - does this actually matter if
the two channels are wired in the same fashion??

(I don't see how it can, but am I missing summat...??)

This is what you're actually doing - or should be. One channel only shown.

If you swap 1&3 (both channels) the pot will just work in reverse.
Swap 2&3 and you will likely get strange frequency response errors plus
possibly distortion near zero.
