Question:

How does the Tremsetter work, Can I still push down and pull back on my tremolo to raise and lower my stings?

Answer:

Yes. The Tremsetter works very similar to a double hinged door; i.e., the door can swing both ways, but comes to rest in the center position. When you let go or your tremolo arm after you have raised or lowered your strings, the Tremsetter automatically returns your tremolo to it's "zero" position.
