Questions in the title

I only ask cos my Fender has 110s on it and sounds a hell of alot louder then my ATK which used to have the edge. I've put a Badass bridge on my Fender but it can't have made that much difference could it?
Also how much does string though increase resonance? Is it a noticeable amount because I'm temped to start doing it, but means I have to switch strings 'cos the ones I have aren't long enough which is a shame.
