I didn't buy these from RS Guitarworks, but it was recommended by Hillbilly in this post: http://www.mylespaul.com/forums/tone...ml#post1490126. I got the Raw Vintage Saddles for my strat last week.
These are probably the most amazing things I've tried that aren't linked to the electronics that actually does improve the tones of my guitars.
Previously, my strat (American Vintage 57 Hot Rod loaded with CS fat 50s) was mushy in the neck (not muddy, but just not very focused), and a little ice-picky in the bridge. The in-between tones weren't much to write home about either.
Now, with these saddles, for some reason, the neck is still as chimey as before, but a lot tighter, and more focused. The inbetween are very sweet now, and the bridge, is bright, fat, and jangly, with no ice-pick! The guitar is also louder, and much more crisp acoustically!
I have no clue how the saddles alone can amount to this change, but it's really amazing how they changed the tone. They're not exactly cheap, but I'd say they were very worth it for this strat!
The next thing that Raw Vintage recommended (as did Billy) were the springs. Those were fully sold out locally, so I'll have to wait for them to come in.
I highly recommend you guys who play strats to go try these!
