Using guitar hero controllers as a source for PCBs

Yeah, I’d too like some more info on this xplorer guitar because it’s cheap as dirt.
I was gonna make a PC/360 stick, but the “normal” controllers are all crazy expensive.

Having “just” 6 buttons is totally fine.

The xplorer seems to have a load of wires going out from it, can you just cut those up and just connect to your buttons? Is soldering required on the pcb? Just the dpad?
I have no problem soldering (well, not anymore), but I’d prefer not to obviously.

One link pointed to a resistor to remove if you want to disable tilt, is that all you need to do? No soldering?

Edit: Oh, and anyone have the dimensions for this pcb?

I’m looking for some info on doing this with the wired Gibson SG model guitar. If anyone has any info or pictures of this being done that would be great.
