It seems that this image is being hotlinked alot. Theres at least three different bands on myspace.com that use it as a page background. I suspect none of them actually play a fretless guitar like that pic features. It seems to show up on the second page of results for a google image search on “guitar fretboard”. I guess thats where people are finding it.

muffin.jpg seems to get linked from a lot of message boards as well.
