If you're playing a tremolo thingi for David Gilmour for example on a Floyd Rose tremolo , it would sound awkward cuz the Floyd Rose would give it a wilder range ... You should try to make weaker action on the tremolo.

Tremolo is one thing you don't really think about when you do it , it just take a while to get used to it , then you'll never look back ... Try practicing with EVH divebombs , and may be some Vai if you're into his stuff (his tremolo work is very advanced).
