oh yea, 1 more thing...did anyone here have try GoPod ? if you dont notice, GoPod is a tweak for uncapped by firmware...i used it now and my Nano sound awesome, more soundstage, even bass roll-off was gone, and got more impact on bass & other freq...or just make it simple, GoPod make the SQ more shine than before (stock)...if you ppl had tried em, how GoPod compare to a real iMod/Gmod ?
There's very little need for a tutorial, iQEM. You have a garden variety of iPod opening pictorial/tutorials, and besides opening your iPod, all you need to do is: solder some wires to the board; drill a hole; and basically make an interconnect with some caps in the sleeving, which there is another tutorial for in this very subforum. After all, we are in a do-it-yourself forum here.
The most damage you could do to your iPod happens while you open it, so the abundance of tutorials for that process should already almost fully equip you to do this mod. Once it's open, solder this and that there, drill a hole, make an interconnect, voila.

Here are some pictures of my progress. I've found the pads I need the DAC to connect to, but I don't know where to grab the signal from. Maybe someone can point me in the right direction.
The DAC of interest. LOUT1 and ROUT1 aren't as obvious as the iPod nano 1G, and only LOUT2 has a visible trace; ROUT2 can't be found. Even the signal from LOUT2 can't be found.
edit: That pin 5 should be pin 4.

this day i had test 2 Gmod (my friends had it) myself and surprised that Gmod doesn't look different from standart ipod...only the blackgates dock line out look different than dock that ussually use for amping...how they do that ? i mean, why joneeboi had to put cap on a tictac box, not copy Gmod or iMod form ? can you try to figure out & make DIYmod more simple ? no intend to push you, just curious about the form factor...that's all, thx...
note:
how about GoPod guys ? no one had response about it yet ?!
As far as I know, the WM8750 and the 8758 are the same. My source of knowledge comes from general Googling. The pinout for this chip seems different from the ones in the 4G and the nano 1G. I tried following the trace from the dock back to somewhere around the chip, but it seems Apple used a 4-layered PCB to get their work done, so I can't "trace" it that easily (get it? *uncontrolled laughter*). I might try soldering to those giant yellow caps on the other side of the iPod and see what my luck is.

Blessed are the feet of those who bring good news!
I figured it out. I feel like such a dork. Refer to the picture of the WM8758. Reading around, turns out the 8758 isn't like the 8750 so much as it is to the WM8978. Those components with the Z on them are the same as on my 4G and the nano 1G, and I can't believe I didn't connect the two earlier. Turns out the audio feeds just come from different pins. Nevertheless, the procedure remains the same. Remove the Z components, solder from there to the line out pads as shown in that one picture above. I think you may need to connect another wire to connect the grounds or something, as the audio is still fuzzy coming out of the line out. It may be a grounding issue, so someone may want to investigate this matter. I tested sound with my MHM, which is supposed to have DC blocking capabilities. Something else is amiss as my left channel measures 1.44Vrms while the right channel sits at a measly 1.0Vrms; for reference, my diyMod 4G sports a commanding 1.5Vrms.
That's that. The adventurous may want to try this on their own while I study for the three finals this week (the last of the three is on a Saturday ). My mind can finally rest from this diyMod hoopla.
