i can't say much...but I did just get them and put them on. I don't know about the tone because I don't play through an amp very often. Compared to the slide-string-through speedloader type of
saddles my guitar used to have, it's much more tuning stable. They're expensive, too, so unless you're breaking strings like crazy at the bridge, I wouldn't bother. I love them on my strat and epiphone cause they really reduced breakage. On the floyd... time will tell
