I am unsure what you want. But I can clear up your question.
On an electric guitar, and some acoustics, you will see a bar that they.call the whammy bar. This is often a tremolo bar by name. The truth of it is it is a vibratto bar
Vibrato modifies music by changing the pitch.It bends wires.
For reasons unknown, tremolo adjust by moving the volume. The real tremolo is inside your amp or in a pedal.
Where the confusion came from is still unknown. But, your tremolo is probably in an amp or pedal. Vibrato is by the bar they sometimes call a whammy bar.
