Conclusion. As you can see, whammy bars are perfectly fine. There is no any harm whatsoever a whammy bar can do to your guitar. Of course, you can notice some tuning stability issues when you use it, but it's probably not because of a whammy bar itself.
Can a whammy bar be put on any guitar?
All tremolo systems have their quirks, whether you use a Bigsby, Floyd Rose, two-point synchronized, floating or what have you. But a new system says it can deliver perfect tuning and accurate pitch bends on any electric…or acoustic, for that matter.
Can you use a whammy bar without an amp?
You should be able to hear a difference in the way the notes sound but it will not sound as good or be as intense without the amp. If you are not hearing any difference in the notes as you use the trem then there could be something wrong with it.
