I tried first the battery without the caps and it did not seem to do much. Then someone suggested that for solid state equipment to add the cap. The cap really did the trick.
By the way, it seems the higher the battery voltage the more it tilts the sound upwards. The 6V lantern battery is the most neutral.
I bought the Capacitors from Radio Shack, they were $1.79 each. I used the thinnest wire I could find, though I am not sure why I did.
