Go to a search engine like Google or Vivisimo. Type in your mysterious component's number/marking plus the word datasheet and hit search. Once you've downloaded your gizmo's datasheet form one of these sites it will tell you about its uses, specifications and architecture. (You may have to do a little digging, but most manufacturer's have free datasheets available on their websites.) If it still looks interesting, do another search using your component's number/marking plus words like application or guitar effect.
Hope this info isn't already obvious to you. (File under: teach a man to fish and ---). Search engines are great for quick answers to basic questions, but probably not as fun as posting a forum question.
