I intend to get my SE modded eventually so I’ve been looking up info on how to do it as painlessly as possible. Perhaps I can help you with a little of my research.
Check out Purplearms “TEasy in 30” video on youtube. It will show how to mod a 360 TE stick, which is basically an SE stick in terms of PCB and wires, to run with the PS3 using a TEasy Mod and a Dual Strike.
With the new TEasy Strike that’s out now, which combines the TEasy and the Dual Strikes into one PCB. Just following the instructions means that you’ll have a modded stick without soldering.
Personally, i have no idea how to install one of the other great mods out the, the ChImp. But I can imagine that it’s just as easy, but requires a little more wire cutting. But I can’t find a good video on how to install it or clear enough instructions (For me atleast, I’m a bit of a worrier if I have to cut something cause I know I’ll invariably ruin it)
