Question

Is it possible to attach a seperate Tremolo arm to any electric guitar...?

Answer 1

No; you have to have the right bridge.  Some guitars, like Gibsons, have a fixed bridge, which won't take a bar at all.  And there are several kinds of tremolos, too.  Not all bars are interchangeable.

Answer 2

A tremolo can be put on any guitar is the guy knows what he is doing.

I do this on a daily basis. If you need answers, email me when you decide to install a tremolo and will be glad to tell you, YES or No and which one to use.

Better than that, I will give you free advice and no need paying for this.
