Question:

What exactly does the Tremsetter do?

Answer:

The Tremsetter installs on your tremolo guitar in the back cavity where the springs are. When you put the cover plate back on your guitar you will never even know the Tremsetter is there doing it's job. The Tremsetter automatically brings your guitar back to its "zero" or starting position. Ordinarily, your tremolo relies on the your string tension pulling against the springs in the back of your guitar. Its a delicate balance similar to the way a teeter totter works. If one side is just a little out of balance, your guitar will be out of tune. The Tremsetter overrides this precarious balancing situation and brings your tremolo back to the exact "in-tune" position.
