This is more for the purpose of it. I know that the locking tremolo have the ability for a whammy bar but are there really any other features because I see it on lots of guitars? I've been looking for a good shred guitar but the locking trem is too cumbersome for me.

a locking trem locks at the nut and at the bridge to help it keep tune when you dive bomb.

Like stated above thats all its really there for....

But side benefits-

You dont need locking tuners and can use some really bad tuners and it doesnt matter also if a tuner goes it doesnt really effect you too much.

You never will need to replace the nut...


Cons-

It can get in the way and sometimes scuff up your hand pretty bad if your going fast up to the 1st fret and forget that the nut is there.

no but it will make dive bombing easier for you because you don't have to retune the guitar the guitar everytime you divebomb.

even if u never use the whammy bar, their just a superior bridge design full stop (provided it is a decent quality trem)
