I've been reading up on the Pro-Sound mod and most of the documents I have found call for wiring it up after the pot (so you can control the volume). But that seems a bit odd to me if the purpose is for recording, because the output should be controlled by your mixer or in post?
I noticed ASM mentioned in another post that you can connect the wires before the pot, which makes the most sense to me.
The question I had was if wiring it up before the pot ends up causing any distortions or any undesirable affects? Otherwise it seems like the way to go (can keep the GameBoy speaker connected this way too).
