Guitar Pad Sound

I have recently noticed an interesting guitar sound often heard in Trent Reznor's music; NIN and David Fincher film scores. I call it a guitar pad, since it sustains for a long time without decaying, like a string patch from a synth.





Here are some examples of songs where this kind of sound is heard:



- Leaving Hope (from NIN, comes in at around the second or third verse)

- Perihelion (from The Girl With the Dragon Tattoo)

- Intriguing Possibilities (from The Social Network - it's in the second chorus where the song picks up in a more powerful way)
