PSP SpringBox is a really surprising plugin that I've already found tons of uses for that I didn't think I needed. Its amazing on guitars. I've been using it on close mic'd mono acoustic guitars and mono synths to give them tons of life plus a stereo image. It really helps revive an otherwise boring, dry track. Even when used subtly, SpringBox makes a huge difference.
