The Wikipedia article about Sonic Youth states the following:
Azerrad writes that early in their career, Sonic Youth "could only afford cheap guitars, and cheap guitars sounded like cheap guitars. But with weird tunings or something jammed under a particular fret, those humble instruments could sound rather amazing – bang a drumstick on a cheap Japanese Stratocaster copy in the right tuning, crank the amplifier to within an inch of its life, and it will sound like church bells"
I actually wired a pair of iPod headphones into the humbuckers on my Squire and played James Taylor through them with distortion and fuzz cranked to +9000, whilst hitting the strings with a screwdriver. It sounded... beautiful... Like, soothing goth rock with electric birds twittering emphatically while rain-nymphs had sex with chickens...
Conclusion, modding is fun and all, but if you want innovation, try the junk drawer.
