The acoustic guitar have a nice looking scratchguard down below and also have a nice looking inlay around the soundhole. We can see a bit of the fretboard to the right of the screen but that's about it. The guitar body is not in full view.
This wallpaper if so the size 1024x768 and if you stretch this it will work well also for you that are running widescreen computer monitors.
Hope you like this guitar wallpaper.
