For the benefit of this who may frequent our forum for information, the differences are so subtle that most folks wouldn't be able to tell in a blind test.
Also a stretch, but I love your optimism. I change almost all my tremolo's to 1-piece bridges but that's primarily because I like the original design. I do believe there *can* be a tonal difference but have never heard it on the many guitars I've 'upgraded'.
Respectfully, I think blanket comments like that might be misleading to those who don't know any better. SE guitars can be wonderful right out of the box for the life of the owner (or the guitar) whichever ends first. The truth is, we like to hot rod our guitars. Its a guitar guy thing to do. And SE's, being so affordable, offer us a great opportunity to make it our own without breaking the bank. Few are the SE upgrades that are necessary.
Just my opinion.
