I used to be outright militant about it. Now, I honestly don't care. A year ago you wouldn't have caught me dead with a guitar that didn't have matched hardware. Now I'm rocking an SG with chrome hardware but mismatched gold pickups and a Strat that has been gutted and has electrical tape covering the middle and neck pickup slots and a p90 in the bridge. And guess what...I scrapped all the parts from extra stuff laying around and both guitars totally rip beyond their original state.
