Whats the point of a tremolo bridge

Question

Like on Mick Thompsons guitars

Answer 1

The obvious answer is the Tremolo arm, which allows for a vibrato or pitch-bend type effect with the sound out of the amp. Also ,Mick and James Root both have locking tremolo bridges, which literally lock the strings in place and that keeps you in tune. No mater how much bending you dish out to the strings, you'll still be in tune. The down side, however, is that they are a b*tch to lock into tune. Once there, you're golden.
