I always thought post pot was soldering to the legs of the pot? Cause it changes the volume if you solder to it. You have to solder along a bit more.

There's also better solder points for pre-pot. You don't have to solder to the legs of the pot, you can follow the trace a few mm and solder to a better pad. Somewhat petty, but eh. Stronger connection nonetheless.

There's just not much point in post-pot, because you should be running through a mixer or some sort of amp anyway, and you'll be able to control the volume through that.

Unless you clean the potentiometer, you can get some unpleasant crackles as well from turning it. Pre-pot all the way!

I have both a pre-pot and post-pot prosound.

The pre-pot is far nicer!

Pre-pot = no volume control for the pro-sound mod, but you can still use the GB speaker using the volume knob as you normally would. A bit louder.
Post-pot = Volume controls the pro-sound mod and GB speaker (so you might want to disconnect the speaker or figure out a switch). Less loud than pre-pot though still louder and cleaner than headphone out.
Note that I haven't done this mod myself so don't hold me to that (hold Kitch to it instead )

I thanks Man, that image is everything! just what I wanted. cheers!!

Cool, that's perfect! Thanks Kitsch!

this is how i've done mine in the past, its louder than post-pot at max volume. thats the only difference really. you loose the ability to control volume from the gameboy, but get a slight volume boost.

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).
