Hello Guys, So I'm new to strats so i don't know if this is normal. I have a vintage type tremolo ( the one that you need to screw in ), and a couple of days ago i've noticed that when i insert the tremolo arm ( i really use it seldomly ) the arm Giggles when fully inserted, the blue line represents the center position, i can move the arm between the two blue lines without it "moving" the bridge... Is this normal ? In this second pic (this should be a cutaway from the bridge), if it's so the arm shouldn't "giggle" as it does... What can this be ? is it normal ? if not .. how can i fix this ? thank You !
