burnt wood effect - help!

I am trying to create an effect that will make letters appear to have been burned into wood - I created a wooden board in photoshop with the help of EyeCandy 4000, found the right color and texture for the lettering, but I cannot get the letters to appear burnt INTO the wood. Used EyeCandy's "bevel boss" but now matter how I manipulate the curve, it always looks like the letters are on top of, instead of burned into, the background. Does anyone have any ideas how to do this?

Just off the top of my head here. If you want the text to appear burnt into the wood.

You could use a cut out text font and then apply a inside shadow onto the text. Not sure how good it would look, cus as i said its just off the top of my head.

Give it a try and see what you think.
